The music is nerve racking. Get rid of it please.

If you still use this, id love to see the test done on the sk5 srk, they claim to be 65 but that doesnt seem right, everywhere i look people are wondering about it. Itd be a popular video im sure

Made in China cheaper and is bad steel blade

Have you ever tested spyderco 10v? Going through your vids to find but haven't seen it yet

Miss you bro

Miss you

What the hell is the noise in the background?!

Wow, it gets calibrated every quarter too ! Cool

This info is more valuable to us knife nerds then most understand. I REALLY REALLY wish you was still doing these test videos.

16hrc omg lmao that tickled me good

I love this stuff very interesting thank you sir i have a PM2 in S110V i will say i was a little disappointed with 59 i thought it would be around 61 or so 😆

PLEASE do away with the music,

Awesome video! Finally a video that hleps put all the higher-end steels in order for me. That said which would be best suited for someone who really USES his knife everyday working in construction, tree services and landscaping?? I have been going crazy trying to find the right blade.

I hope you do these tests again loved all the information and knowledge

New Sub.. have you ever tested a knife from CFK?

Here's the average numbers for each blade: Grey PM2 20CV - 60 Red Manix2 20CV - 60.65 Grey Yojimbo 20CV - 60.3 Red Para3 M390 - 61.15 Red PM2 M390 - 61.5 Blue PM2 M390 - 60.65 Cute Little Thing M390 - 58.15

You still around? I sent you a bunch of knives over a year ago now, hoping you are OK.

where are you i miss your channel

Watched the entire video rocking my head to the music..... Now I'll be singing them all day long. Thanks for the info here man. Appreciate it.

Any idea what the bradford guardian's test at ?

RIP rusty

Where you at bro

is anything beter then maxamet ? :D rex 45 and k390 close behind it or ?

I know this is ancient by now, but I like to rewatch your videos, and want to salute ya! Unfortunately I was reminded of the embarrassing 55 on that Immorrtal. I have a legit Immortal, and grabbed a "tribute"/clone because I too revel in the ridiculous, and wanted one in black. I forget what the steel composition was, but even if it'smmm

Miss your videos man

Change muzik

Absolutely incredible song at the end when you tested Manix2 Cruwear witch im just sharpening now😍 What is it?

Just got my hands on an m4 manix, I'm so happy with it. Totally addicted to manix in general and now have 7 variants

What do you charge for these tests?

Stupid music...0

I just picked up a manix m390 second run of the exclusive brown g10. Was wondering if you ever tested anymore of them.

SRV!🤘

Where'd you go? No uploads for six months?

Love my voyager even more now!

Why no new uploads?

How do I send you knives to test? I love this stuff! Thanks for all the videos.

Filmed with a potatoe. Cool.

Have you done any of the swaybacks yet? I'm curious what they brought the cts xhp to I'm guessing 61

Subbed. I think I've been going to spam bud.

You have my sub, check me out if you can, thanks.

Kurt you doing ok?

"This is the first that addresses the notion that all machines have a +/- 1 point variance. Because of the way that information has been presented, many believe that to be a tolerance built into all machines" To be clear, there are two main types of variances : -random -systematic Random variances are things which will change every time you run the same test even on the same sample, even if you were to run it on the same piece of steel. These are due to physical limitations of the machine and the operator, every machine will have a random variance tolerance IF it has been calibrated. Random variances can be reduced through proper statistical methods. Systematic variances mean the readings will not change with an operator doing the same test on the same machine, but IF you go to a different machine, or switch to a different operator, then you will get a difference. If a machine was professionally calibrated it would also list the systematic variance, a LAB rated machine would have both independently, but you could also just get a total. If you really want to understand the limitations of HRC testing, then read this report from the guys who literally wrote the book on standards testing (NIST) : nvlpubs.nist.gov/nistpubs/Legacy/SP/nistspecialpublication960-5.pdf Note the list NINE sources of error when talking HRC measurements and this doesn't mean a mistake in procedure, this means you are professionally trained and you do everything right and there are still NINE factors which can cause your result to deviate from the true value of the material. To be blunt, if anyone thinks they can take a Rockwell machine, and know the true value of hardness to within 0.1 HRC, this is just fantasy, and any QC operator would tell you that at BEST you could get within an order of magnitude of that. Send things to a professional NIST certified lab and watch their reports. For reference, Buehler sells HRC blocks. Their 60 HRC calibration block is guaranteed to be within 58-62 HRC. They are an accredited supplier (The Buehler-Wilson Hardness Calibration Laboratory is accredited to ISO / IEC 17025 by A2LA). This means when you set your machine to 60 HRC based off that block, it could be as much as 2 HRC points high or low.

Nice tests, very helpful, thank you! Have you tested cold steel 4max scout?

I wish you could get you hands on that K2 now. I softened all of the edges on that knife. Not enough to change the looks, but man it's so much nicer in hand. And the action, after I cleaned it all up and added detent ramp, is the best washer knife I have ever handled!!! I told Kevin I already miss the knife, he said we might be able to work out some visitation rights!!! LOL Thanks for all of the kind words!!! BJ's PM2 look really great, not bad for a Hillbilly!!!

That was a great bunch of knives, I was fondling my REX45 & St Nick's 4V Manix 2's while watching!!!! The music was fantastic as well. Thanks for all that you do!!!

Another really good video Kurt!!! Robs definitely a great guy for sure!! Congrats on the CRK!!! Thanks for sharing brother!!!👊👊👊

Badass batch of knives!! Thanks for all your testing Kurt!! If Spyderco makes a native chief in Rex I’ll probably have to grab one!! Thanks for sharing brother!!!👊👊👊

Another great video on a very cool group of knives. I will be right there with ya with the Depends and the apple sauce. Thank you for the video and for the guys sending them in. I have a batch coming.👍

Great video with some incredible knives. I wish the 10V and K390 would be in Rex45 territory. Thank you guys for sending them and thank you Kurt for testing and filming them!

Thanks for what you do brother! Can’t wait to see what’s next!
