Was reading this in General. Some awesome knowledge dropped in there. Very well explained JT:thumbup:

My question to some of the custom makers here. Have any of you ever re- heat treated any one of the Becker line up to bring it up into the 60's? I'm thinking a BK5 or 15 at like 62rh in the kitchen![]()
I'm pretty sure you'd want a small-carbide (or no-carbide), small-grain, high-hardness steel.
1095CV would be an ok candidate. 1084 takes a stupid fine edge with high stability and very little chipping. However it is not super abrasion resistant. So there's a trade-off.
VG-10 would be a great choice for a proper kitchen knife for these reasons. It won't hold that edge forever, but at 60Rc would make a fabulous santoku.
1084 Would do extremely well also, but obviously not be stainless. It's awesome at ~60Rc. 62 is pushing it for many common steels. You're likely to get chipping unless it's a super-tough variety.
I'm wouldn't be too keen (har har) on re-doing the BK-5/15 for kitchen duty. Yeah, they're sweet, but a true kitchen knife should be thinner and allow you to get the whole blade on a cutting board, which means more finger relief is necessary. You don't need a very hard blade to carve a large critter, which is what the 5/15 would really excel at.
Also, re-doing a Becker would raise the hardness and give you SOME advantage with 1095CV's very keen edge, but Becker geometry is a compromise between cutting ability and toughness. In the kitchen you want a much thinner blade except on a cleaver...
Hopefully JT will weigh in and correct me where necessary.
