I ground the end of the talonite into a chisel and ran some tests. First, grinding was very strange, I am using a 4" disk grinder, and unless I looked very closely, there were no sparks. The talonite was harder to grind than steel, but not prohibitivly so. I got the edge very close to where I wanted it, and then honed it down with a norton 2 sided stone. The stuff, though hard to grind, seems to sharpen more easily than many of the alloy steels.
As a chisel, it worked rather well, reducing a 1x4, ~6" ,long to nothing w/o resharpening.
I also ran a destructive test, hammered it straight down into an anvil w/ a 5lb sledge. The very edge actually cracked off as a tiny wire, but there was no other damage. i'll scan some pix when I get a chance.
