I've got some of the scale ground off. It's oversized in all dimensions,which means more grinding, especially on the tang, which is pretty thick, but it was getting too small to hammer without distorting too much. I could have monkeyed with it and hammered it thinner, but the weld on my rebar failed so I was down to using vice grips, so..... got it straightened, made sure I had length, and called it. I need to go pick up some vermiculite tomorrow, to anneal it and run it through some thermal cycling, to refine the structure in the steel and release and stress. If it's going to warp, I'd rather it warp while it's oversized. Then I'm going to glue a copy of the sketch straight to the blade, profile it, grind some, then harden it.
