I find a dull knife more dangerous than a sharp knife. The sharp knife will go where and do what you make it. A dull knife you might have to force a bit and that can result in a harmful slip. Anyhow, I save Tony's band-aids just in case.

When I wrote that story for KW last year, Tony said they send ATS-34 and most of their CPM 440V to Paul Bos for heat treating, but they heat treat most of their D2 to around Rockwell 61 at Wilfred Works. Not sure about the 154.

The swayback is in M4 and the edge has held up really well when I've used it. The BP is 10V and I just got it so I haven't used it that much.

Very Nice set Mike

Thanks for the great information and the fine picture of a couple of indestructible knives. Either of them would last a lifetime and serve you well. I'm jealous!

Thanks for the nice comments, but Tony did all of the work.

I'm probably not the best person to ask, but I know that knifemakers have been using M4 in the knife cutting contests and it has done real well.

This Website also has info on 10V:

Great site. Thank you.

I see "heat treated by bos" on many knife selling sites. I see this on upper price range knives as well as mid range priced. He must be very good. But on his website "their" website Tony and Reese Bose, he shows his Rockwell hardness tester. So just a guess he may do some of his own. But I am with the guy that said send them out. For these people, like Bos, this is all he does "I am assuming that is his main business" so he does it best. Paul Bos must be one of the best. I have see the Bos name on many of the better knife selling websites specifically mentioning at the end "treated by Bos"
