From Useless Rasp to Useful Marking Knife


I have a set of really terrible wood rasps that I bought very cheaply years and years ago. They're bad rasps.

I finally got around to making the flat one a useful tool by cutting it up and grinding off its teeth and turning it into a marking knife.

The only issue with it is that the divots left behind after grinding it flat means that it can't be ground sharp with a single bevel; it has to be beveled on both sides, or else the divots will create notches in the edge. I can live with that, but it would be better made from a very fine mill file or an old chisel.
