Yes, I just used a belt grinder to take the set off both sides, and just one quick pass on each side of the blade, held in your fingers will do it. I hand hold the blade to cut screw slots, as it only takes a couple of passes. In fact, mine which has been serving me for about thirty years is shortened and one end ground narrow to about 1/4" and sharpened like a chisel for cutting the wood away from barrel key holes. So it cannot be mounted in a frame.
