When my first knife warped during heat treating Hoss told me to do my grinding after HT, and I had a hard time with the concept because it was hard enough to shape the blade when it was soft. He was, of course, correct and this second one got the lions share of the grinding after HT, and it seemed to go more easily than when in the annealed state. Go figger, some people you should just believe.
I did still get some warp, though, and I clamped the blade to a rusty old file with an old saw blade for a shim under the tip when tempering, and it came out nice and straight!
I don't know what you would call this style of blade, though.
