to harden the edge of the POS khuk a neighbor gave me.
It started out 16 1/2 inches long, and was a shaped steel club with a blade so soft that a paring knife could peel curls of metal off the edge with little effort. The handle was the thickest full-tang tree-trunk I've ever held. The weight of the tool was centered about an inch in front of the handle. If you didn't use your whole arm, the khuk wouldn't move...I didn't measure the full weight.
Right now, it's about 14 inches long, the handle is contoured for my hand, a substantial amount of metal has been taken off the bottom of the blade, and inch-plus off the end, and another inch or so off the butt. I put in a new cho since the original one was taken off during the excess metal removal process.
I am NOT skilled. I used what I had at hand, and will try and emulate tempering over a charcoal fire to harden the edge.
Since the price was right, and I would never use it as it arrived, I have no compunctions about messing with it. If I can get any kind of hardening on the edge, I think I will stop before I screw it up. Then, I will use it.
