Just this morning, I came across a set of 4 much-abused, no-name chisels in sizes 1/2 to 1 1/4/ in the garage. Someone had pounded them, likely with a hammer.
I oiled the steel, buffed the rust--but kept the patina--trimmed 3/8" off the end, slimmed them down with a pipe cutter (no kidding), a chisel, and a rasp. Then tight fitted a copper ring to give them some protection.
Stripped the ugly yellow finish and replaced it with some darker stain. Added a little oil finish and put a nice edge on them.
They are worth keeping now.
I bet with a little attention, some of yours are too.
