Magnacut at 62 HRC. 10" hollow.
Will soon have carbon fiber scales.

I am of the camp that finishes my knives nearly 90 percent before heat treatment. But I have the luxury of sending my knives to Peters for heat treatment. Nonetheless I am fascinated by Natleks methods! Obviously he has some serious grinding skills that the rest of us don't possess!
 
Hey everyone, I'm new here. Just recently picked up my first hydraulic press, a nice blue 15 Ton that I bought from Dave Lisch. Been learning to use it and making a few new dies, hopefu6ill have some nice Damascus and integrals coming out of my shop soon but still a lot to learn. Cheers!

Why just for thin steel ? This two pieces are 4.5mm thick CPM S30V hardened on 62 Hrc .Straight as it can be straight . Now I need to decide which design the knives should be and continue with the work. There are even advantages to this method. There is no fear of cracking, warping of steel , hardness after HT protocol ......All I need to know is there before I start to work on steel . It's not very pleasant when after so much effort to finish the knife, something happens during hardening and the knife ends up in the trash...............I am right ?

I understand your point of view, but I don't see why not to do a whole series of operations before tempering, for example: profiling the knife, and drilling. You could also make a coarse grind of the blade. These are steps that take you little time and that avoid stress on the already hardened steel.

mknife , all that is valid for soft steel in HT process ? Holes are potential stress point , shape of knife , grinded bevels can be reason for wrap .......etc .Almost every hidden tang shape knife I quenched get less or more bend in ricasso/tang area. Then I start to leave tang unshaped and bending no more in that place ...........
I don t know , maybe I make to many knives from hardened steel so I got used to it , but I like that way .Clean and predictable job . Watch this kid ............... I do the same thing and i like it , what can I say ? Anyway , I just state how I do it, no one is obliged to work the same way . Do what you think is best for you. In the end the only thing that matters is the final product not the way how we get there , right ?

He even make folder from hardened M390 steel

I make this one from already hardened M2 steel .ALL parts are from 64 HRC M2 steel . Blade , liners ,spacer between liners . At no point during the making I run into a problem because I work with hard steel .

I often send blank rectangles of steel off for heat treating (usually with at least one handle hole) and do the profile after they are hard. Belts eat hardened steel and if I need to remove a lot, I use a angle grinder with a diamond cutting blade to rough it out more. I cut farther away and then grind to shape. It's not too bad and that way, I can send a large batch out for HT and have options in terms of what I make with the blanks. I can go from a hardened blank to a finished knife in a day or two as well, so when I have them on hand, I can get orders done pretty quickly! If I send a blade out to HT fully profiled, I am locked into that shape, where if I leave it very oversized or rectangle, I can do what I want with it.

An interesting approach. May have to try it. Do you get any warping around handle holes?
