Back at school, I was reminded of the "crooked carving knives" I saw on this site. I love it when people provide lots of details on how they make things, even when they're trying to sell them, because it makes it a whole lot easier for me to try to make them. So I tried making one.
I used an old sawzall blade that was missing some teeth. I didn't actually use the one in the picture, I neglected to take a picture of the snaggletoothed blade before grinding it. Boy, those things are amazing. They sure take some kind of abuse.
oil quenched and tempered with a propane torch. The temper came out okay, but I'll try using an oven next time.
I've been using this knife on and off lately. It's got a lot of flaws and could use revision. I'll model my next one more like the knife I linked to earlier.
