    After all the slingshot projects went bad over the weekend I decided to make some simple knives. This one is a small carving knife. The steel is from an old jigsaw blade shaped with a grinder and sandpaper. Heat treating was done with a MAPP gas torch. The handle is a Longan stick with the bark left on. <br><br><a href="http://m.flickr.com/photos/[email protected]/7307264518/lightbox/" class="postlink" target="_blank" rel="nofollow">small knife 1</a><br><br><a href="http://m.flickr.com/photos/[email protected]/7309739342/lightbox/" class="postlink" target="_blank" rel="nofollow">small knife 2</a>

    Nice job. Unique design, but I could see it having some uses.

    interesting. I've wanted to make a few large knives, but I'm waiting to find some old lawnmower blades (at local thrift stores,etc) I figure they are not made from crap steel ? and other than having to heat treat the steel post forming, I figure I can "cut" the shapes out with a die grinder & a metal cutting blade, but I guess I'll see - once I find some old mower blades !!!

    I'm not sure about mower blades. I'm sure they are good steel, but I wouldn't imagine they would be tempered mostly with toughness in mind. Meaning I don't know if they would have the appropriate hardness for a good knife. I've never heat treated before, but I get the impression it's one of those things that's easy to do a decent job at, but very complicated to perfect. The thing about things like saw blades, files, etc. is sometimes only the really old ones are good for knives. Sometimes modern ones are only hardened on the cutting edges and the rest is left soft.

    Farrier's rasps. Big size and will heat treat and temp well. You'll get about 58 on the rockwell scale. Farrier's go through a ton of them per year. Find a local one and ask nice and explain what you want them for. <img src="http://illiweb.com/fa/i/smiles/icon_biggrin.png" alt="Very Happy" longdesc="1">
