Half inch?!? What kind of blade is it?

860C for 20 min and 2 hours in 175C should give you 55/56hrc.

My guy also stress relieves this steel prior to heat treatment (I have three Knives in k600 steel). I think he makes what they recommend in the steel brochure.

Good gravy! Half inch!!? Oh, you have got to post pictures of that when you are finished.

I remember starting in knifemaking, and having the “thicker is better” mentality. But as I’ve grown in the discipline, I’ve actually gone completely in the opposite direction. I have found “thin” stock to be the better choice.

Unless it is a shear for a paper mill or a bull dozier blade, .5" is twice the thickness of any possible bladed tool I can imagine.

Can you elaborate on the blade shape/style/use/etc?
