Nice. Not every handmade knife has to be made of the most cutting edge super steel, or the most expensive, rare handle material with gold and diamond insets. I enjoy making knives the most from items that would eventually end up in the trash bin. I have several feet of bandaw blades that a friend salvaged for me. Aside from being on the thinner side, the steel is pretty tough, holds an edge for a decent amount of time, takes a nice fine edge, and can be worked without heat treating it. I assume the sawzall blades perform in a similar way.
