Yeah, it's not much, but it's something.

The complete spreadsheet is gold, though.

Very cool thread!

Naively, I would have expected the Cruwear to come with a bit higher HRC as the steel is very though.

Seeing the hardness at which Spyderco tends to run their S30V (around 60) and M4 (62 - 64) I am starting to understand why the edge retention tests done by some YT folks (my hat is off to all of them for all that work) didn't quite reflect the CATRA edge testing done by Larrin which suggests that at the same HRC, the S30V delivers a bit better results than CPM M4.

If anyone is still wondering, if DLC coating affects HRC testing:

Apparently, there seems to be no difference.

Anyone test a Maxamet Sage 1 to see if Taichung is running theirs as hard as Golden's Maxamet?

Any ideas on the St. Nicks para 3 lw? I'm guessing that it would be a higher HRC than the original SNK P3.

Looks like he needs a refresher on the standard practices and procedures and how to straighten up that dial.

Pretty cocky video thumbnail for someone with little reading and experience with hardness testing.

Looks like we're going to get all kinds of wacky test results as we watch Alex try to reinvent the wheel.

As I've been watching you deep dive on instaG on controlling the variables in hardness testing, I realize that a lot of the info on my list is pretty unreliable.

I wouldn't say I regret starting this thread, but I would hope that people take the numbers with a HUGE grain of salt. It's just not reliable, and testing one blade doesn't mean a different blade will be the same.

I don't see it as cocky at all. Most major knife manufacturers DO wish the HRC of their blades were kept secret, this is common knowledge. Strange choice of words.

Perhaps not a great "look" Shawn.

I'm left wondering: How do you know how much reading experience he has?

And in regards to "wacky test results", he says he calibrated the tester prior to doing the knife in that video; and in the next video, he shows some of that, with the cal'd/test(er) plates.

(If I've got my head up my ..., don't spare my feelings, and please enlighten me. I'll hopefully be smarter for it, and I'll still luv ya. We're both long since grown)

That said, what is it he's is not doing correctly? Constructive criticism vs. just Criticism. Me personally - I'll take Both; but I am curious as to what he is doing wrong?

"Cone of Truth" is a strange choice of words when you don't show the calibration and are showing in the video that the ASTM E18-20 standard is not being practiced which was written to make sure that everybody who does hardness testing is on the same sheet of music paper so that our hardness values can have some form of agreement between different testers and operators. Details matter if you're using your hardness test values to call people out.

u.w.
Is it a better look to censor knowledge? There's nothing stopping anybody from learning how hardness testing works and from getting a copy of the ASTM 18-20 to understand what the best practices are for the most accurate results.

I don't want to be that guy to call people out.

Keep in mind, I don't have to share and for the most part I keep to myself.

But if somebody is misinforming people whether it's through negligence, ignorance or incompetence,

Wouldn't you like it if somebody with the knowledge said something?

Perhaps there's a better way on my part to bring this up but sometimes it's nice to be direct.
