After I uploaded the 'Making a Custom Knife for the Antarctic Research Mission' video the other day, a few people on Reddit had questions about how Kydex fared in extremely cold temperatures.
I've used my knives in temperatures down to about -15ºC, but my customer in this case is expecting to see temperatures down to about -30ºC, so some more testing was required!
I was fairly pleased with the results overall. The retention and fit of the sheath were unchanged all the way down to at least -40ºC. Kydex definitely gets more brittle at those temperatures, but you would have to subject it to some fairly serious impacts before that actually became a problem.
For extreme-duty service in extremely cold weather I'd likely start recommending a leather sheath option, but for regular use my opinion is you'd be just fine with Kydex.
Materials and tools used in this video:
Dry ice is normally available from places that also supply industrial gasses. Look in your area for suppliers like Praxair, Camcarb and so on.
Infrared thermometer: amzn.to/1t1oTWE
Ball peen hammer: amzn.to/13vjrqB
This video was filmed using the Panasonic Lumix G6 w/ 14-42 Vario X lens: amzn.to/1vzonRT
This guy is one of the most organized, inteligent sounding RUclips's ive ever seen, I wish he'd upload more.
Thanks very much Micah! I want to start making more videos again but I'm very short on time at the moment unfortunately!
This is EXACTLY the kind of thing we need to see. Excellent. Subscribed!
Thanks!
Interesting. Would like to see leather at -40C.
I did some testing around this at the same time, just didn't want to show the sheath as it wasn't one of mine. The leather was still flexible even at below -40ºC, didn't seem to have any issues.
I am so impressed with the instructional capacity of your videos and the integrity of the data you put underneath your videos. Also the level of technical expertise you demonstrate in knife making or sharpening is inspiring. I am a high school teacher and have used your videos in the strangest ways to elicit ranging pov on 'process' and the importance of it. The lessons always work and the kids love it.
Big thanks for improving the way we do thing Gough !!
Hey thanks Tom! That's really awesome, I appreciate you taking the time to comment!
What sort of stuff are you using my videos for in school? Let me know if I can ever be of help with something in particular!
Love your videos!! You make beautiful knives
+Travis Volz Thanks very much Travis!
Brother that was fantastic and really opened my eyes I will now no which way to steer my customers in that condition take care mate lee. Luckylee from bb
For the record I still think Kydex is still a very good option for 95% of use cases, you'd have to wail on it pretty hard to get it to break. For military customers though I think other options would need to be explored.
Check psyched substance on youtube, you and him remind me of each other. Love you both 😂😂
Thanks bud!
Your videos are always awesome! Very informative!
Thanks
I was expecting to see missing drains on the scrap sheaths :-)
Haha, I did have some but I chucked them just the other day! I need to remember to keep all the scrapped parts for testing!
just one question. where do you buy your kydex from? i live in BC and can't find any good places that have reasonable shipping
What thickness of kydex do you use? Also would you be interested in making custom scabbards for hand saws for arborists?
Hey mate! I use 0.080" thick kydex. At the moment I don't have any time to take on any custom work, sorry mate.
Superbly done. Thank you again for sharing your tests and findings.
Thanks mate, no worries!
Surprisingly lack of -40 degree memes.
I will remember for next time! 😀
The kydex held up better than I thought it would, a heck of a lot better than the vinyl used in truck seats anyway! The coldest I've ever been out in is -38°F, not including windchill, and the seat in my truck broke like it was made of glass.
BTW, have you ever thought about doing a shop tour video discussing what tools you have, about what they cost and why you chose them? I think that'd be interesting!
Hey mate! -38ºF is COLD! I'm surprised the truck seats failed like that though, maybe a combo of UV exposure and the cold?
I plan to do a shop tour soon, not sure when exactly though.
Love the videos and your knives are amazing! Could you make a video on how to start with knife making on a limited budget? Thanks and keep up the great work!
Hey mate!
I have a couple of videos planned that would cover that, I just need to get time to make them!
-A
I wonder how it'd do if you got it coated with rino liner material. Their website says it won't warp/crack down to -40 degrees. Not sure if that includes whacking it with a hammer though.
Hi, I noticed your personal knife has a black finish on the blade. How did you add that? I am looking to make my own and I have watched all your videos and love them! But nothing on the finish!! Thanks!
Man, I'm running a marathon of your knife videos. This Resolute knife is one of the most beautiful knives I've ever seen. Great work, keep up!
+Karl Veliki Thanks very much Karl! Will do my best mate!
As usual, interesting and well-made video. Thanks. Of academic interest only to me, Africa doesn't do temps down that far ;)
I did some informal high-temp testing all the way up to 55ºC as well. The retention of the sheath gets lighter, but still works as intended.
Gough Custom So I think we can safely assume that the human will fail before the Kydex at both ends of the temperature spectrum :)
Johann Rissik Haha, yeah pretty much!
wow I have to say you really do take your time and I enjoy your vids, best knives 10/10
Thanks mate!
Thanks Aaron...Great add-on video. Kydex is only rated to -20°F (-29°C) per ASTM Testing (www.kydex.com/uploads/files/kydex_tb_121-b_minimumservicetemperature_061412.pdf) which means it probably has about a 15-20% buffer. I think your tests were much more severe than a notch test and definitely higher than a ASTM Impact test but may have been a bit more worst case real world. Wind chill down there can reach to -70° or lower and prolonged in those ranges would definitely effect it. Personally I would think your sheaths would handle most of it based on your 24hr soak and the spring retention you still achieved and is a testament to your forming and fabrications methods! How about the scales and glue? Thanks for addressing this!
pjsalchemy wind chill only effects living things. It is a measurement of wind flowing over skin causing evaporation.
***** Gough Custom in affect correct, only because the object cannot go below the ambient, but at what ambient might this person have to be in? The problem for humans is the metabolism trying to compensate. Sheaths don't have a way to compensate and therefore move to the extremes of their tolerance very quickly because of wind chill which can create other issues for the material. Also there are "living things" down there that have adapted metabolisms to survive the extremes of that environment.
The definition clearly states objects as well as living organisms: "a quantity expressing the effective lowering of the air temperature caused by the wind, especially as affecting the rate of heat loss from an object or human body or as perceived by an exposed person." It's about heat loss at the surface from the wind effectively drawing heat from the object/human. The physics of it (convection) is real however we Perceive it as humans. Antarctic mean temps range between -13ºC to -57ºC from the coast to the south pole.
The Kydex sheath is a thin material and depending on where its kept, how rapidly it will equalize to ambient based on the formulary for wind chill, what ever that is, and will be exposed to a rapid change in temp and states of stress if exposed to the limits above. I thought Aaron's tests were quite valid considering he doesn't have a full blown ASTM lab.
Fair enough, the rate at which the kydex cools could theoretically have an effect on its integrity, however, his tests lowered the temperature far faster than ambient temperature is capable of regardless of wind speed. In the case of objects, calling it windchill is highly misleading, as in this case its simply convection, whereas windchill is really specifically about living tissue. The perfect example for this is frostbite, in order to get frostbite the temperature has to be below 32* F because frostbite is tissue freezing and dying, but even if the ambient temperature is higher than 32* F frostbite can occur of windchill is below freezing. If we don't make this distinction we'll have people trying to tell us that air passing over a cars radiator is windchill. Not that I've ever had anyone attempt to convince me of that...
TL;DR I agree, his tests were exemplary for the equipment he has and will prove more harsh than an excursion across the antarctic, unless the customer tends to use his sheath as a hammer...
Awesome test. That was like worst case scenario. I'd take it in extreme cold without worries.
Worst case scenario for sure! I don't think most people randomly get pelted with hammers when they're out in the snow!
FUCK YEAH CANADA.... wish I had money to actually go to Canada
It's a little cold up here at the moment! Spring and fall are the nicest times to go camping, not too hot, not too cold and minimal bugs...
good point why not you do the same test with leather ;-)
I id actually, just the sheath wasn't made by me so I didn't want to show it in the video. It was fine all the way down to -50ºC. I'm not a fan of a lot of leather sheaths because of the clasps/straps used to hold the knife in place. The scandinadian style molded leather sheaths seem very cool though.
молотком стучит, рядом термометр электронный скачет на столе
Your fucking great! I want this knife and the d6 knife from DBblades, that’s all I want
+Zilch71 thanks bud!
The conclusion is don't smash your kydex sheath with a hammer in -40 degrees Celsius conditions. It makes sense. I can live with that. ;) Good video.
Haha yeah seems pretty reasonable when you put it that way!
But lets be clear. I enjoy you did test the kydex. I enjoy you did test the steels in another video. I enjoy your video's and your knives. P&p to Europe is expensive and of course we have 21% tax to pay for American and Canadian products, so your knives are expensive for us back here in the old countries. In extreme cold conditions leather would be better but in basically all other conditions kydex is better. Leather looks prettier though.
You see. The life of a knife enthousiast is not all roses. Choices have to be made. It feels like divorce sometimes. ;)
What basic things do you think are required for knife making? And how much would it cost to invest in?
You can get started with very simple tools if you're patient. A cheap drill press is a great tool, then some basic hand tools like a vise, files, hacksaw and so on. Check out the other videos on my channel as I show a lot of things to get started cheaply.
Weird question Aaron, but do you happen to be from Australia? I was picking up an Aussie accent.
+Jaden Bass Hey Jaden! I am Australian, yes! I moved to Canada in 2006.
Cool video! Just don't hit your sheaths with a hammer if you're in -20 degree temperature and you'll be fine! haha
Haha, agreed!
Nice product seeing as the temp of dry ice is -78.5℃ it will probably last at any temp.
Yeah I think it should be fine pretty much anywhere! I don't think the sheath will have gotten all the way down to -78ºC because air is a poor conductor of heat, but who knows! I have no way of measuring temps that low!
That is extreme with the hammer testing to be honest it took multiple blows to start to damage it when negative forty. In my opinion it held up very well, and functioning was not effected.
Yes, I agree. I wanted to find out what the limits of the material were though and I feel i have a pretty good idea now!
Can you send a knife to Mexico City?? I really want one of your knifes I'm sorry if my English isn't good lol
If you customs/import laws allow the knives then it should be fine. I won't be able to take new orders until mid next year though unfortunately.
How well would it stand up to extreme heat? Say 120°F?
The retention of the sheath will get lighter as the temperature goes up, but other than that it won't hurt it
Holy shit I dig your knives. I have yet to see one I don’t want. Ps cut the piss out of my self ... hell yea !!!🙌
Haha thanks mate, glad you like them!
How does the knife click in everytime? Is this a special type of sheath?
+breezyflow1 Yes, the sheath has 'lips' that grasp the finger groove on the handle... The sheath and knife are both specifically designed to allow this to work.
how many personal camping knifes do you have
DragoChronicSmoker42 Just the one shown in this video now, the green one in my sharpening video was stolen.
I love your vids on knife making mate 👍😊
Thanks Kenneth!!
Can you give us the mold of the knives for those of us who want to do it at home please?
No, sorry mate. I don't share the design of my knives as it would weaken my ownership of the design. You are welcome to copy the knife from photos providing the knife made to that design will not be sold.
You have these knives for Brazil? I would buy one. Thank you.
I can ship to Brazil provided your customs laws allow my knives. I'm not able to take orders at the moment though because I'm swamped. Have a look at my website for more info: goughcustom.com/
Gough Custom value which the knife?
Glicerio Mariano This model is CAD$320 including the sheath and belt loop.
Do you have a website i can go to buy a knife you made.
Nathan Hunter My website is: goughcustom.com/ unfortunately I don't have any knives for sale at the moment, I'm hoping to be taking orders again sometime around the middle of the year...
Awesome experiment! What thermoplastic material were the sheaths made of specifically? (Kydex, Boltaron, Holstex, etc.?)
Thanks for the awesome video!
Hey Mark! The sheaths in this case were made from Kydex. I have tried the others and I still like kydex the best. The others seem a bit softer in my opinion...
@@GoughCustom thanks!
Great video, thanks!
You're very welcome Ray!
hello Gough this is awesome. only have one cuestions what edc blade you carry ??????
I have carried a few CRKT knives in the past, but overall I haven't found an EDC in happy with unfortunately...
have you tried the spyderco paramilitary 2
just wondering, if you supercooled the sheath, then brought it back up to room temp, would it regain it's shatter-resistance, or would it be a permanent change?
MrGnarman Once the plastic is brought back up to room temperature it returns to normal, at that point you can hammer on it all day with no damage.
Gough Custom cool! thanks for the response!
Any thoughts on Boltaron over Kydex? I've read that a few makers have made the switch from Kydex and that Boltaron is tougher and more resistant to temperature changes.
+Jimmy Grey Hey JImmy! I haven't tried Boltaron, and hadn't heard that about it actually, I will have to look into it!
What I would *really* like to do is to make the investment in having an injection mold made for producing my sheaths. That way I'd be able to make them out of a material like glass-fibre reinforced nylon which will be an order of magnitude tougher than anything I can thermoform in-house...
Gough Custom That would increase production ten fold! I'm sure it's very time consuming making all those Kydex sheaths. I personally don't know anything about Boltaron, a few guys on forums praising it. Kydex is plenty tough for me though.
Where i can buy these knives?
Alex Bichler At the moment I'm totally booked up unfortunately, but you can get more info on my website: goughcustom.com/
Hi, great video again thanks. Any chance you're planning a video about your new shop? It looks all brand new and would love to see your new toys!
I might put together a shop tour at some point soon as a few people have asked about that!
Great can't wait. Keep the videos coming I've missed them lol. Thanks again
So, I live in Scandinavia. Its not uncommen to have temperature way bellow -20, with peaks around 40. We dont use much kydex over here, but it looks tempting. Would you suggest going with a traditional leather sheath or would it be fine to go kydex?
I think you would be totally fine going with Kydex... Unless you're hitting it with a hammer it is plenty strong and continues to function just fine!
Gough Custom Thank you for your help and time :)
Your products are works of art! This Artist-Engineer-Craftsman combination is excellent! I hope you have someone with marketeer-salesperson skill set as these skills are (unfortunately) equally important these days. You could also use an intern as well.
Question: Is there any technical reason you didn't use a single kydex sheet and bend it at the back of the knife riveting just one side, or is it just aesthetics?
Again, excellent work, congrats!!
Thanks mate! I'm actually pretty decent on the marketing side of things too luckily, worked in that industry for quite a while. The main reason i use two sheets of Kydex is to ensure i can get the seams perfectly flush, i also want rivets on both sides of the sheath to allow for attaching belt loops and so on.
Your videos are an inspiration sir
Thanks mate!
Nice
I believe this is the reason that Fallkniven use Zytel sheaths. There was a fellow who had an interesting Channel that I used to enjoy that has since closed it down, who specifically did a video about this and indeed spoke with the owner at Fallkniven (whose sheaths get a little bit of ribbing for their looks from some people) and the owner confirmed that this fragility of kydex at extreme temperatures is the sole reason Fallkniven don't use kydex.
However, as you clearly demonstrated, it took deliberate abuse for the sheath to fail and its functionality wasn't affected prior to the abuse.
And yet, you can see why a company would not use kydex after this knowledge. For me, I would just be aware of this and take care of it, like any tool.
And speaking of which I wonder how fragile the knife would be at this temperature; at -40c you should be looking after everything in my opinion.
Take care
Ben
I have continued to use Kydex for my sheaths because this testing showed that it was certainly tough enough for the purpose... Zytel would be better, but I think it's overkill in this case. The steel of the knife would definitely be more brittle in the cold, particularly down around -40ºC
I have an eye like that,too.In the beginning i used to walk into signs and light posts all the time!But now my brain can exclude what the "funky" eye registers and all is good.Hahaha!!!
Love yr knives!
Thanks mate! Yeah it took me a while as a kid to get used to it, but it's not an issue now!
I wonder about the endurance of leather in this test, My presumption would be that it would not last as long in the same tests. I have seen kydex sheaths within ballistic nylon and perhaps the insulating value would protect the kydex more. Also knowing how poor ballistic nylon sheaths seem by themselves to be on most blades due to poor stitching but I do think it would fair better during your hammer test.
I think in the short term leather would hold up better, and in the long term probably worse... My guess is the leather would crack after getting deep-frozen dozens of times, but who knows!
Ideally what I'd like to do in the future is have my sheaths made using an injection mold, as that will let me use stronger materials. Something like fibre-reinforced acetal or nylon would be amazing!
Interestingly I am told the next greatest sheaths will be made from pineapple fiber of all things. From what I am able to Discern is has almost identical traits to leather but much higher reported resistances to heat and cold. I will be curious if the traits work as advertised.

increible...un maestro...para mi los mejores cuchillos del mundo!! un saludo desde españa gough
bruce lee Thanks very much mate!
muy grande!
That Was amazing.Thanks very much.İ m intiresting with hand made knifes in Turkey.How can i buy this knifes?
Thanks mate! You can get more info from my website: goughcustom.com/
Hey Aaron, love your video’s. When will you next have stock available on your website? Are you still making the Resolute?
Hey mate! Thanks! I will have another batch available before the end of the year, but they'll be hard to get as there are already a lot of people waiting, next year I plan to ramp up the number of knives I'm making so they should be easier to get!
What thickness of kydex are you using.
Grant Bawden I normally use 0.080" thick kydex for all my sheaths.
Gough Custom Ok I was just wondering it looked a bit thin I also use the same thickness of kydex. By the way I love your videos they are super helpful! I just made my first knife over the weekend and it turned out great. I am having trouble with the acid stone wash if you could post a vid of acid stone washing that would be awesome!
I really like your commitment to making a quality product. Too many makers rush their items. As a knife maker myself I’m impressed with your attention to detail man.
Thanks dude! I appreciate that coming from a fellow maker!
Conclusion; don't go at your sheath a ball peen hammer. Great video, love your work.
+raymond overson haha yes, always good to avoid!
both kydex and leather gets brittle at temperature down and below -30
some zytel (nylon alloys) are designed for those conditions
thanks for sharing!
I did some testing with leather on the same day as I made this video, it was fine all the way down to -50ºC, showed no sign of becoming brittle...
It might be a different story if the leather had gotten wet somehow, but dry leather certainly seems to be fine with low temperatures...
could you make a video tutorial on making a sheath out of kydex as I am trying to make my own.
+Demonic Dukky Hey mate! It's something I have on my todo list, but it's probably still going to be a while before I get round to it unfortunately.
Gough Custom okey dokey bud! I look forward to seeing it when that time comes :)
I apologize if this question was asked before, what affects does the extreme cold have on the steel and G10?
It shouldn't have much effect on either of them. The steel is chilled down to -75ºC during the heat-treatment process which helps avoid potential issues with the steel at low temps later. The G10 is very strong and fully supported by the handle, I also don't believe it gets brittle like the kydex does. In short the blade and handle should be relatively unchanged even at the low temps.
Craig on the Crawling Road channel tested Kydex, Zytel and leather sheaths in freezing conditions, but not extreme temperatures like you've done. Your test is good, but it doesn't consider moisture. watch?v=6LhBfUbPtfs
Yeah I watched his video a few days ago. I replicated his tests with one of my sheaths... Because the fit of my sheaths is so close it definitely causes issues if the sheath is full of water and then frozen. That said the sheath does drain well so you have to work a bit to get it full enough of water, I had to hold it sideways to prevent it draining before I froze it. It's definitely something I'll be taking into account when redesigning my sheaths in the future, but for the moment I think it's ok.
Pretty crazy all the stuff that ends up going into making a knife/sheath!
Gough Custom Indeed, love watching your videos!
Yes, the more I think about it the more I realize that kydex-sheath is probably good enough 99% of the time. If you have extremely low temperatures you probably don't have a lot of moisture anyway.. I'll try putting a Kydex-sheath through a Norwegian winter and see how it fares, should be about the same as your Canadian winter.
And I tried the water & freezer test with one of my knives again last night, but this time instead of forcing the sheath to retain water by holding it sideways, I held it upright and let it drain like it actually would if you were getting rained on while it was attached to your belt. I put a bunch of water into the sheath, but almost all of it drained out straight away, even with the knife in there. Then I froze the blade again. This morning I tried it and it popped right out with no problems, barely any harder to remove than normal... So I think that even with my close fitting kydex design you're not realistically ever going to get it glued in there by frozen water, as the water drains out well before it would have a chance to freeze.
Great test Thanks,Coldest we get in Tasmania is about -15..
+THEDRAGONBOOSTER8 Kydex would definitely handle those temperatures just fine!
Dont take this into offence but i think its very impressive to make these perfect knives that are so sharp and beautiful, with a "lazy eye" i just think its cool how u do it, keep up the good work :)
Thanks! It actually doesn't really have any impact (that I can tell) on the workshop stuff, makes things a little harder in some other areas like sports though.
What made is the grinder ?
The grinder is a KMG made by Beaumont Metal Works
This is my favorite knife making channel for all my knife questions I always go to this channel and watch a video
+All MERRICA Thanks mate! Glad you like my videos!
first video I watched with your voice, straight away picked up the aussie! fellow aussie here, keep up the great videos mate.
+Dylan Curnow Thanks Dylan! Will do mate!
dry ice is around -80 c
+yohaijohn Yes, I assumed though that the thermal transfer would not be perfect and that the sheath would be at a higher temperature... Unfortunately I did not have equipment to measure temperatures below about -40ºC or so.
Excellent video!Very informative.
Thanks!
what size are your resolute knives? Are they 5 in. or 4.25?
The current model (REsolute MkIII) is 4.25" long.
I was gonna place an order on a knife, but I ran into a moneyproblem, but before I apply for basic military training here in Sweden, I'll place an order! Love your knives!
When you start basic training you will probably be issued a Fällkniven F1 if you try for infantry service. It is a pretty good knife. And hello from Norway :)
Thanks mate!
Mother army will issue you a Mora of some sorts which you will use and abuse. Buy a good knife when basic is over, before then it's a waste.
And the day mother Army issues the infantry with F1s is the day this soldier drops his pack.
can u test the opposite now? how it handles under extreme heat and humidity
meaning for desert and tropical climate, like 50 degrees C and about 90% humidity
ogilvy85 I've done some informal testing at high temps (55ºC)... The retention of the sheath is definitely lighter, it would be fine when used normally on a belt, but I wouldn't want to have the sheath upside down in those climates. I haven't done high-humidity testing, I don't imagine that should affect the sheath itself though.
You shouldn't be recommending leather, you should be recommending to get the F&%@ out of -40c weather! Do I hear a hint of an Aussie accent??
Haha, when I read the first line of your comment I was like "????" and then I read the rest, nice comedic timing there :)
I agree that -40ºC is cooold. I'm an aussie, but I live in Canada now... Have been out in some pretty low temps. Down to -15ºC or maybe -20ºC it's ok if you have good gear, lower than that can start getting uncomfortable! I'm sure it's fine if you have the real gear for the temps, but I hope not to be exposed to it enough to need it!
Gough Custom No problems with brittle kydex here in QLD brother. Love your work
airmitch10 Thanks mate! Been a long time since I've been to QLD, closest I've got in a long while was Byron Bay... Need to get back there at some point!
How would i go about ordering a knife from you? Your work seems excellent and id like to order one!
Hey Brian, glad you like the knives mate! Right now I'm totally swamped so I'm not taking orders. You can sign up for my mailing list if you'd like to be notified when I'm taking orders again: goughcustom.com/
Would temperature extremes as low as this permanently affect a knife's temper? (After letting it return to room-temp before using it, of course.)
+HipposHateWater No, it shouldn't have any effect. It is possible for it to have an effect, but it's very unlikely for any knife that was properly heat-treated.
+Gough Custom At -50-60f (-45-51c), the blade would become more brittle. I am sure it would have no effect on the temper, but if used at that temp. for a while, there is a good chance the knife could be damaged. Probably not from cutting branches, etc. but I would not use it to pry open cans unless you had too. Of course, at the temp. the can is frozen solid already and the contents are coming out of the ruptured can.
+paralogia Yes, low temperature embrittlement is unfortunately impossible to avoid in any hardenable steel... Even a low of engineering steels will be much more brittle at very low temperatures!
The knives should be fine for preparing food, butchering game or whatever but I wouldn't use them for chopping or prying at those temperatures, that's for sure. Opening cans likely wouldn't be a good idea either as you said!
This issue can be remedied somewhat by making the knife blade much thicker, but I don't like to make knives that way, I prefer to make them thin so they perform well!
Hey Gough, got any injection molded kydex to run through the same test? Incog uses that process to manufacture their holster, and state that injection molded kydex has the advantage of no degradation to resilience over heat pressing kydex on to the object that it will be used with. Just wondering.
I actually don't have any on hand I don't think. I'd love to do an injection molded sheath, just don't have the gear right now to make the molds. That will change next year so it will be something I likely try out!
I feel silly, I just remembered that unpressed kydex basically has the same resilience as injection molded. So in case you were wondering if injection molded kydex would hold up better, you can just do the test on a raw sheet.
***** Interesting! I actually chilled a small scrap down to -50ºC and then hammered it, no issues with it at all... Because it was a small piece it was probably heating up quickly though.
I love the look of your knifes vut have you ever think of making a tanto.
Thanks! For most of my customers a tanto would not be very useful... I try to make knives that are as utilitarian as possible and the tanto blade shape does not work well for a lot of tasks, including skiving, butchering, skinning and so on...
Thank you for replying to my question. I never thought about
It for all of the different and verying ways.
Interesting test Aaron. I hadn't spotted this when I made the post on the forum. I think we could safely say that day to day stuff would not cause the sheath to break. Only a 2 month spell in those temps would tell if it would cope long term. I suspect it would. It would be interesting to see if Kydex have any data on it, or maybe see if they're interested in your test? You might bum some free Kydex off them! Graham.
Hey Graham! In the long term I'm likely to start looking at other sheath materials like zytel. I'm actually considering whether I should be looking at building an injection molding machine so I can make 1 piece molded sheaths, that would certainly open up the possibilities!
Gough Custom I've not heard of that Aaron, I'll give it a Google. What about leather, there are some quality leather sheath making video's out there? Do you plan to sell your knives commercially?
***** Leather is nice, but I don't much like the fact that you have to use retaining straps, as they're always getting in the way when you're unsheathing or resheathing the knife... I do plan to sell the knives commercially, I do already in fact although the volumes are very low. My hope for next year is to improve my production methods fairly substantially in terms of efficiency and consistency.
well that answered my question! thanks
Excellent!
Where did you get the dry ice? I cant find it anywhere . Live in ontario
There's a couple of places. The place I go is called 'The Ice Man'. If you search for dry ice [name of town] you should be able to find a place!
Any of the welding suppliers that distribute bottled gasses do dry ice, Praixair, Air Liquide that sort of thing.
Where abouts are you in Canada?
In Toronto!
Cool Im just outside Ottawa!
..and why are you testing this?
Because one of my customers is going to antarctica and I needed to confirm that my sheathes would be fine at low temps.
Gough Custom very nice testing for your clients! great job on that. Compliments
You live in Canada ? If so were I'm In Ontario
Yep! I'm based in Toronto...
If ur that cold for a few days ur sheath will be the last thing to worry about lol
I know right!
I would be equally interested to see if the cold had an effect on the steel.
Good question! It shouldn't as the steel doesn't really change at those temps.
Would the durability enhance if you put leather or steel liners inside the sheath?
Possibly if there was a leather liner, but leather also retains moisture and encourages rusting unfortunately.
I see....
I got that idea from the kydex sheath that First Edge Survival Knife comes with.
It has steel liner between the kydex.
And because of that if the kydex were to break the sheath will still retain together(or at least until the steel liner doesn't break) whitch is good since that knife was made for the navy SEAL guys
Aluminum or titanium would be better no rust
Boltoron, and done.
***** I thought Boltaron was the same as Kydex?
Thanks , well done, respect.
+Ivan Quin Thanks Ivan!

Um dia vou ter coragem, de largar tudo e me dedicar a essa profissão, pois adoro.
Hey mate, I have a kinda irrelevant question here but, why is your right eye like that? Are you blind on your right eye? It's a bit awkward sometimes because you don't know where to look when you're speaking into the camera :)
I was born with a lazy eye.
Gough Custom does it affect your depth perception, like while driving?
Andrew Stewart Yes, but for the most part I've learnt mechanisms to compensate.
Gough Custom There are glasses that can correct your lazy eye.
Great testing :)
Thanks very much!
interesting video!
Who beats on the sheaths um no one Good video tho u make some great stuff
Probably no-one, but it's important for me to understand how my products are going to respond in all manner of conditions!
