It's great for edge retention, but it's just so damn hard to sharpen. I want to make a knife out of some super expensive hastelloy bolts I have but my first attempt failed as I couldn't get an edge on it (88.5 HRC) I literally burned through 6 belts trying to get the edge profile. If I manage to make a knife with it I would love to send you one to test out. If you would be interested in that.
I know how expensive they are, but surely a Rockstead needs to go through your lab one day? They make such a big deal about their rope cutting performance
I'm so glad I finally got a Mako Rex 121 from Creeley. Hoping to find or make a nice custom scout style sheath for it. It's just a bit big for the pocket with the one that comes with it. Great content as always! Love the new house btw.
I thought I was watching an episode of Stranger Things with that intro music.. Extremely interesting result btw... I have a hypothesis. If the carbide component of any steel composition is the element most resistant to wear then by logic it would be the last item to "dull" when cutting. This means that all of the other material is simply there to hold the carbide in place and since it is a powder metal, it is very evenly distributed. Effectively, this test was carbide vs carbide. Perhaps this is not always the case as the steel composition just does not have enough carbide to be equivalent in most knife blades, so maybe REX 121 is the minimum tungsten carbide % to be equivalent of edge retention to that of actual straight carbide.
Cavedog my thoughts exactly. From reading the Rex 121 composition list it really is a super alloy that is used to cement a bunch of carbide aggregates togethers. Think of it like those diamond abrasive tools that use aluminum as the cementing agent. It makes sense then that the carbides both give up the ghost at the same time as ultimately they are the same ting, just held together by different cements.
Regarding the wear on your arm, maybe try staying better hydrated? When I have had jobs with high repetition tasks the ache in the joints diminished by keeping well hydrated with electrolytes too. Even some guitarists with tendonitis mention this helping.
Good job. Might be a better result because more sharpening gets to the tougher more stable steel as outpost76 is finding to be the case. Go easy on your shoulder now.. do something earthly like d2 from ganzo. I know many people would love to see how that "còokie crumbles" :7 maybe even get it new and put this sharpening theory to the test.. see does the number of cuts really dramatically increase in the first few sharpenings. And I told you to save that shoulder.. lol.. sorry but this would be an amazing series and discovery to see. (Hope you do it:)
@@CedricAda yeah, I saw that. I'd like to see Christie sharpen it , then you test it on your rope, then super steel Steve do the same. Have each sharpener put what they think would be the optimal edge for the rope. Idk, just to see if some how you could get it even further. I hate that non steel knife thing lol! Great review Peter!!
Im yet to see a folder. Apparantly its very intense on the grinders and such, and a bit too finnicky to heat treat in bulk, but there are a few smaller fixed blade guys using it in smal batches. That being said, I woud expect the mad scientists and Spyderco will pick it up eventually.
Can you find a knife made in SM-100 (Titanium Nitride)? I dont think it will keep up with these but I've been interested to see the results for wear and toughness.
Boo Yah, nice one mate. Pretty cool to see how that edge performed and the title equalled. How annoying that it was a matched number of cuts 😂. Seriously you can't fake that shit.
When the lab coat went on, I knew shit was about to get REAL. Maybe it's the two glasses of rum I drank but I think I have officially gone Ultra-Nerd, because when the Rex121 went past its previous record I raised both my arms in the air like I was at a sports arena, ahahahah. Blood, sweat, and tears (verb), you give us your all, Pete, a legend in the making.
I got a 20 year old cutting board I still use that looks brand new. It's a solid 3" thick end grain maple board. Every few years I just sand it down past the surface marks and it's like brand new again. It doesn't take more than 20 mins start to finish with the right tools, oil it up, wax it up and it's good to go for more years of use. It will probably last another 20 years if I continue keeping it dry. The issue would be the glue degrading or the blocks expanding/contracting too much.
Did you see the steel testings on the Ganzo FH21 from Luv Them Knives?! If not please watch it! I hope you will test that D2 from ganzo in the near future.
Cedric & Ada Gear and Outdoors just trying to figure things out, new to all this stuff,but think that your work is outstanding and I enjoy watching all the different out comes ,so keep up the great work ..l look forward to seeing more. Thank you
Obsidian can be extremely sharp, but it's fragile and has little wear resistance. I work with it all the time, if you want a sharp edge just make a new flake, but it's only good for a few cuts. It's just impure glass, nothing magical about it.
prob won't get an answer to this, as it's an old video, but: hypothetically, you're in a survival-tactical-knife-fighting type situation... does that thin tungsten carbide blade hold up when you're slashing and stabbing away at your foe...? i mean, will it get caught on a belt and just snap the blade in half? how about when whittling wood at your camp? i'm just wondering how abusable that thin tungsten blade is... ("toughness")
What kitchen knife steel is ideal if corrosion resistance is paramount and edge retention. Almost totally unimportant.( I have no issue touching up steel every time I use it).
douglassteltenkamp LC200N is my ideal if you can find a maker. Gary Creely could possibly make you one. Its basically rust proof and maintenance free, holding an edge about as long as S35vn in my experience. Elmax or M390 would be great choices too.
Came across your channel last week been watching ever since I bought a Benchmade 551 - 1 CPM 20cv can anybody tell me what angle I should put on the blade
Rex is the winner in my book. Why, you may ask? Because I'm the king of my universe and I say no ties. Plus that other thing isn't a knife its a letter opener.
Greg M Rex 121: C: 3.40; W: 10.00; V: 9.50; Cr: 4.00; Mo: 5.00; Co: 9.00; Mn: ?; P: ?; S: 0.03-0.12; Rex45: C: 1.30; W: 6.25; V: 3.05; Cr: 4.05; Mo: 5.00; Co: 8.00; Mn: 0.30; P: ?; S: 0.06; Si: 0.50; So the rex121 has about double the carbon, 75% more tungsten and Triple the vanadium. Its really a wonder they can get all that in there with the other stuff!
Mike Gault absolutely! Ive sent one to michael christy to play with on some of his high tech benchstones so im looking forward to what he comes up with
Impressive video Pete... great thorough info as always... on a largely inane side note... and maybe it's just me (I'm certain it is in fact) but everytime I hear REX steel I can't help but visualize a steel with tiny vestigial arms, massive hind legs and a bad ass attitude 🦖... Well now I'm irritated... that emoji sucks. Come on emoji developers... I mean he's the king of fucking dinosaurs... the damn plate of spaghetti has more detail...
I recon the sandrin dellatore will have a better edge retention than the tck 2.0 cos of the blade geometry. If you wanna hurt your self (and your wallet) then you could invest in that?
I’m here from the future doing my research for the new Sage 5. You’re still the man, Pete.
Same. Just put my pre-order in today.
You would take Rex over Magnacut or maxamet?

So one asshole gave you a down vote. That was a LOT of work Pete! Your tests have really become a great reference. Thanks for this database sir.

I don't find it unsatisfying at all. 1540 with a knife you can actually hold and use for real-world tasks? Yeah, that's outstanding!
Congratulations to all involved in this! Gary Creely, Nathan, and our hero, Pete!

Some Brawndo and he'll be fine.
Great To See what we would expect based on how close these two stack up!!! Cain vs Abel!!!

Thank you for the fantastic video as usual. You always put out great content.
Awesome video Pete. Great job brother. Take it easy on yourself tho man. Don't hurt yourself so you suffer for the rest of your life. Good day brotha.
Nice work
3 people wanted him to fudge numbers so that steel would win. upvote for honesty.
Can you find a knife made in SM-100 (Titanium Nitride)? I dont think it will keep up with these but I've been interested to see the results for wear and toughness.
Matt Nelson buy a knife in sm100 you know how much those cost lol
@@bp-hx9ts Yeah unfortunately they are pricey. Perhaps we could all be so lucky ;)
LOL Rex-121 is some hard ass cheese.
"Steel is like cheese!"
That is why I come here! LOL! Keep up the good work!
Do you have a tier list for pocket knife blade materials? Wed all love to know what the best metal is according to your opinion
Simply outstanding

You need to test a BBB handmade Rex121 sport trapper.
Lo_Que I think he is getting to making me one in 10V. I think its likely to swing at least with maxamet, maybe this too
Lo_Que Rex 121 from bbb is at 71hrc he wouldn’t ever stop cutting
I'll pay that. However, I am really annoyed that now my 'bright shiny object' brain NEEDS a Rex121 bladed knife. DAMN YOU KNIFELAB! DAMN YOU TO HECK!
I literally just learned of rex121. It's been around 5+ years?!
This is insane Pete 😂😂😂 That cutting board has seen more cuts than anything I’ve ever known and its still going

@@jeffhicks8428 In another 20 years it'd be cool to see how it's held up!
That’s awesome !! You can get that edge back on the rex121, on the tungsten? Not so easy.
"Steel is like cheese" lol the quote that broke da interwebz
I just wanna know what the music for this video is, especially the opening song
Sam Brown the opening song is ‘another medium’ by toby fox and the song during the test is ‘megalovania’ also by toby fox
Did you see the steel testings on the Ganzo FH21 from Luv Them Knives?! If not please watch it! I hope you will test that D2 from ganzo in the near future.
Love your videos. Just a small question about the edge angle. When you are saying"a 12 degree edge" is the 12 degree single side or both sides?
per side! sorry I always mean to specify that but I always forget!
That was unbelievable! knife lab history in the making lol. Take it easy now Pete
What do you do with the rope fragments afterwards..?
Just wondering how the thickest behind the edge both are and are they at the same edge bevel angle
Alisa Digout no theyre very different as I said, not a real direct comparison, just seeing what each can do
Cedric & Ada Gear and Outdoors just trying to figure things out, new to all this stuff,but think that your work is outstanding and I enjoy watching all the different out comes ,so keep up the great work ..l look forward to seeing more. Thank you
I would love to see sm-100 testing. Sad that it’s so expensive
After Garry Disher's Wyatt, and Cate Blanchett, you're my favorite Australian.
“Cheese Gromit, cheese!” Thanks again for the fun and info..
You are the man . Thanks for the vids
Wow
.. never thought steel would keep up with tungsten...
Did you ever do any obsidian knives? Would be interesting to see how that holds up.
Obsidian can be extremely sharp, but it's fragile and has little wear resistance. I work with it all the time, if you want a sharp edge just make a new flake, but it's only good for a few cuts. It's just impure glass, nothing magical about it.
@@bobaloo2012 Interesting. So it's only used for very specific situations then I suppose.

Have you used one from dulo knives?
Couldn't help but laugh when I saw this video.
has anyone done a folder in rex121?
did you manage to get an angle off the sandrin
harrison strapp its difficult, it seems like a primary bevel of 11° per side but then theres definitely a slim microbevel of maybe 15° or so

man, I'd love to have a couple blades for my hand planes made of 121. maybe laminated to keep costs down...hmmm.... :D
You poor thing. Go test some Z-hunters to rest your hand
Was Maxamet out back then ?
You worked for that one..
Came across your channel last week been watching ever since I bought a Benchmade 551 - 1 CPM 20cv can anybody tell me what angle I should put on the blade
i think a 17-18 degrees per side would suit most daily uses. If you find yourself carving with it, maybe go up to 20
@@CedricAda Thanks for the information I got a Spider CO sharp maker and I put a 15ﾟ On it it just didn't seem to work Out
I guess dub step never dies...
can you please test 52100?
Love my mako great knife
Enjoy the video Pete 👍
What is the downside to rex121? Usually there is a trade off. Is it prone to rusting easily?
Since a high percentage isn't iron but rather rare earth elements, it's extremely expensive and hard to work with.
its not stainless but not particularly prone to rust. Its just difficult and expensive, as Don above refers, I think
Rex is the winner in my book. Why, you may ask? Because I'm the king of my universe and I say no ties. Plus that other thing isn't a knife its a letter opener.
