A chisel must have a sharp edge free of nicks if it’s going to perform well. But this edge can be easily damaged, especially when tossed in a toolbox for jobs away from the shop. Instead of using a large tool roll, I made edge protectors for each of my chisels.
You can see that they’re just a piece of plywood with a shallow groove cut to the width of each chisel. A piece of hardboard glued to one end protects the sharp edge. And a recessed, rare-earth magnet holds the chisel in place.
