A friend of a friend found this in his dad's shop and new that I am a woodworker so he gave it to me. It says "Swiss Made" on the handle and "5<--<-<-" on the blade. The blade width is 2 3/8" (60mm) and has a shallow curve to it.
What kind of chisel is it and what is it used for?? I can guess for carving slightly concave shapes?
