What is the steel that we are working with here? Is it air or oil quenching?

And do you have a good 2x72" grinder? If you do there really isn't any need for you to soften them....

Doug & Ray sorry i took so long to answer your answers, lol.

Doug for the life of me i can't believe i didn't put the steel, its Aldo's 1095 and these were canola oil. I have since bought Parks from Kelly Couples (nice guy, recommend him to everybody). Even in the beginning i seemed to get good results with the heat treat (canola heated 120). But these grinds are laughable. The spine is thinner than the handle ect.

Ray,
I do have a KMG, had it for awhile. Still learning to get more out of it. Do you think flattening the handle down to blade thickness (with dunking often of course) is easier? The blades are bush-craft style if that helps any.
I have the hanging around for reminders of what not to do.
Thanks guys

If you just have to straighten a little bit out then I would just grind the blades cooling often. Like every other pass on the grinder. It might look a bit odd to have the handle thicker than the blade unless it's an even bevel from the back of the handle to the spine. Work slowly, as in grind a little and check a lot. If the blade does get over heated during the grind you will have to go back and re-heat treat.

You could bring the handle down to the blade thickness but, in this particular case, it might be easier to do a tapered tang. Start from the beginning of the handle area and taper the tang down to about 1/16" at the butt end. This takes a lot of the weight out of the handle and puts it forward into the blade where a bushcraft knife should have it. It also is easier to taper a tang by hand than it is to evenly reduce the thickness by hand ...

Hey Thanks Guys. I was reading your response Ray and i always stayed away from a tapered tangs because i was afraid of ruining a good piece of steel. But this is a perfect one to practice on. Thanks again Doug and Ray.
