CRK heat treat question

Bijluvsblades said:
Thanks for that. I understand what the hardness testing is, but I was more thinking of a) that Tuber’s accusation of the ratings being false and b) let’s say the rating is off, does that give credence to his broader assertions about the blades being poor vs ‘properly’ heat treated.

Regarding his methods and anecdotes of drilling, I find that silly given the gravity of his accusations. I’m wondering if anyone has better data from an accepted process and what that data and conclusion is.

Prior to buying I read many accounts of 35 steel being comparatively soft but purposefully so for ease of field sharpening and to reduce warranty events from breakage. I can live with this as I use a Dozier D2 fixed blade for real camping needs and something bespoke for hunting/field dressing.

Hardness testing would certainly show if CRK wasn't hardening their blades at all and were left in an annealed state, which is preposterous yet the guy in the video suggested just that.

I'd like to see evidence that the video guy actually drilled 300 of these knife blades, what he's using to drill them, etc.

There was an old thread where a forum member was hardness testing knife blades. IIRC, they tended to be slightly softer than advertised or on the softer end of a given range.

The ol' HRC mafia. What happened to those guys?

If I good remember blade hardening DO NOT contain whole blade !!!
Cutting edge only.
So drilling somewhere else is a BIG BS


BTW - who that expert is ?
Trollist Extraordinaire :^D

We got here several genuine knifemakers, just waiting for their resonse ...

You do not “good remember”. very few knives are differential hardened and the ones that are make a big deal of it.
 
The S35vn sebenza's are rated 59-60, anywhere in there is within spec. According to a podcast I listen to, atleast one of the guys had his sebenza HRC tested and it came out to 59. That's a good hardness for the exact reasons you stated. It's a tough compromise from a maker's viewpoint on how to harden their blades. A few points too hard and you have a lot better chances of getting more knives back on warranty work, too soft and you get lower edge retention and unhappy customers. Not only that but they have to keep in mind who's sharpening their knives and what equipment the majority of their customers have. I think 59-60 is a good all around work knife hardness myself. Would I like it if it were a tad bit higher? Yea, but it's not my decision.
 
I mean, has the guy ever used a CRK or does he just drill them? Other than a few micro folds after use that came out with stropping, I've never had an issue with hardness on the edge with the various CRKs I've owned. I'm no expert, but I'd guess it'd be pretty obvious to the user if a blade was under or unhardened steel.
 
I did not have much luck trying to drill a budget krups stainless blade (CRKT Kit Carson) using a tiny high quality drill bit in a mini drill press. It just made a mild scratch in the bead blasted blade.
 
If he's selling the blades with perfect holes on them, Spyderco could sue him too no?

If he's not selling 'em, 100 - 300 crk's would have run him what, $30k - $90k+, just to drill holes in blades after buying 'em? So even already "knowing" that their heat treat was garbage after the first 10 or so $300+ blades, he just kept giving 'em his money 90+ more times?

The entire video sounds like nothing more than a bullshit Chris Reeve hater monologue if you ask me, with no actual validity outside of the word of a guy who says so... For Christ's sake he doesn't even know what kind of steel Buck uses, but he's the new authority on steel hardness?
So should I believe the random guy with a YouTube video, who for all I know bought some knockoff imitations off fleabay, or should I trust the multitude of CRK owners, as well as my own experiences with my 2 CRK's...?

I think I'll trust the YouTube video guy, he has a dog, probably wouldn't lie...

Now that would bring conclusive sunshine unto the matter wouldn’t it? He flat out states CRK are lying about their knives. He’s accusing them of fraud.

They would also be in a position to prove their HT process and claims to establish a strong burden of proof in their claims against his claims.
