>>1408202I use old crosscut saw blades for material removal knife blanks. The current one I'm sourcing is about 0.046" (3/64") thick. When cutting it, I use water to keep the metal cool so it doesn't lose its temper. The same goes for grinding the edge. Thus, no heat treating needed.
You can usually find old "antique" saws at thrift, second hand, and antique stores for fairly cheap. The carpentry ones like this one that are dull are usually the most common and thinnest. Antique circular saw blades that do not have special tips will be completely made of tool steel and are really nice for thicker knives. The ones with the special tips will only have the good steal in those tips and the rest will have lower quality steel. Those are usually more modern.
