I was thinking that I don't really want to grind away at the blades I buy already for handle treatments, so I've been building up my work bench, I now have a grinder and drill press to go with the belt sanders (thank goodness for Harbor Freight!) and would like to progress from making handles to shaping blades. What about going to say the farmers market/auction and buying old steel tools and blades to shape into knives? Can the steel be usable as is? Like an old mower blade? I'm not looking to create sellable items necessarily but would like to make something that's usable. I'm quite certain I'm not the first to ask this, but I haven't found that info yet. Any suggestions, comments and or warnings?
