I looked for the answer, but google was not much help.

I just replaced the blade in my japanese saw and want to use the old blade
for making a few kitchen knives (nothing fancy, just want to give it a try).
I'm really impressed with these saw blades and I think they would make fine
knives. The blade is a 250mm Bakuma from Woodcraft ($8.50). The metal is too
hard for a file to cut and the little dremel cut-off wheels disappear
quickly. The website says that the steel is "impulse hardened" to RC63. The
blade is about .020 thick so it is about right for a paring knife or maybe a
steak knife, it is flexible enough to make a nice fillet knife.

I would like to cut the knife blade profile without annealing the steel (to
preserve the current temper). I'm not sure how to do this - the cut-off
wheels are slow and I'm not very accurate cutting with them, plus it would
"eat a lot of wheels". If I anneal the steel, I'm not sure I can properly
harden and temper the knife blades.

Anyone have some guidance?


Thanks
