CRK heat treat question

[Angus McGunnigle]

Weird……..especially the part about tossing the blade on the dash of a car on a hot day………..weird.

This is a fascinating thread. Can't wait to see the end.

Hi all - I’m sure this has been covered elsewhere and if so please point me to the correct thread.

But if not…

I came across a YouTube vid of a chap who drills holes into CRK blades for a different style of knife opening. His perspective was that because the CRK blades are so easy to drill they are poorly (if at all) heat treated and the Rockwell ratings are phony. This goes for 35 or 45 steels.

Has anyone recently Rockwell tested their blades? Is this rationale at all valid?

Thanks

You ever use a CRK? Did the blade steel act as expected?

I hope you don't "trust but verify", despite literally all evidence showing no need, with everything you come across.

I’d think that after 30+ years in the business, with no signs of sales slowing down, CRK makes a bona fide good product.

But that’s just my opinion

Happy New Year chaps.

I’m of the opinion that the only valuable addition to this thread is some actual post purchase HRC data for those inclined to find out or share.

I’m sure I’ll love my CRK knives and hope you all enjoy yours in good health for ‘22.

Cheers

Hey, same to you bud!

Speaking of enjoying a CRK, when I use mine, the S35vn performs on par with knives from other companies in the same steel. Same with sharpening. So, based on that, I know my CRK has a heat treat, and is treated well. No need for an HRC test. And certainly no need to get all paranoid on the subject because of some wacky youboober.

How about your use?

Guy sounds like a butt munch.

Damn, so my Sebenzas are not hardened??? Well wtf?

Just think how well they’d perform if they were hardened

You think you’re upset, wait until Dcdavis finds out. He’s gonna be pissed.

Makes me reconsider everything I thought I knew

Probably why his tanto 21 snapped.

Maybe I should sue them?

wouldn't it bend and not snap.....soft vs. hard

Bingo. Ive got a kershaw dividend I had several years ago. I used it as a screwdriver and the tip is still bent to this day

As much as I like the spidey-hole opener, I can't see drilling them into every knife I buy. Every time you do that a knife designer cries powdered steel...

And Sal has to talk to his lawyers since most of these clowns don't ask permission to use his trademark

 

[Hackenslash]

The mystery is solved! It turns out the YouTube YoYo was actually drilling holes in the Titanium Handle Slabs.

Nothing to see here. Move along.

Like was said, if their HT was bad, or they weren’t treating them at all, the world would have burnt at this point.

I can only speak from my own experience. In 2007 I bought a small regular, and it was significantly worse in the edgeholding department than other knives with S30V blades that I had at the time (Spyderco, Buck, Benchmade). I sent it to CR and they tested the RC and said it was in spec. Then I sent the blade to Paul Bos for a better heat treat. It is noticeably harder now. Paul told me that he targeted 59.5-60, and I trust him on that. CR said that they targeted 58-59. And with a ±1 for RC testers, it could have been 57 in reality, which is where I think it was because it was so much softer than it is now. Paul tested it before the heat treat and I never asked him what he got.

There is a Paul Bos heat treat separate from buck knives. I belive they are in California.

 

[Danke42]

Yeah Paul Bos is a person and a magician in the world of steel when it comes to ap;lying a heat treatment to a blade.

Anytime you see his name it's worth every penny.
