Thanks guys

Yes, I promise that I'll tell you about the comp. It's held in Roskilde (near Copenhagen in Denmark, Europe ) the 18th and 19th of June

@bruno I guess you are right :/ When I hardened it, it "potato chipped" by the toe. The only thing I could do was to grind the blade down until I got past the crooked part. This almostly destroyed the blade, but I had to use it or not compete at all but I probably took a bit more off, at the toe, than on the heel. I've seen the same thing on old, really used blades, worn down by decades of use -.-'
You can also see the crooked part on the blade without scales.
when I sharpened it, the edge goes a really long way up on the blade. It's because the blade is so thick after grinding away the crooked part.

HSL asked if he could see a pic of the face. This will show you what i mean. first, i ground it on the belt grinder to grit 80 and hand sanded it to 600. I dont have any finer grit belts. aproximately half a cm up on the blade, it was 0.1 mm on the thickest part. then you can guess how thin the edge was.
I learned not to heat treat / harden such a thin blade. It needs to be thicker. RULE OF PHYSICS!!! learned that the hard way. You can see more pics on my photobucket:
