Within the last few years I have become a huge fan of Japanese chisels. They are simple to use and maintain and they take an edge like no chisel I've seen. This was a set that I picked up and never really used. There is a makers mar on them, but I don't remember the name. They are white steel which is easy to maintain and holds a great edge. The handles are Japanese White Oak and the hoops have never been set. Comes with 9mm, 15mm, and 25mm.
