Mr. Carving Knife (chisel)

From the manufacturer:

A convenient carving knife for carving sculpey and epoxy putty. The blade is thick and is not easily broken, and the main body is made of duralumin, so its durability is excellent. The well-balanced weight does not cause stress on your hands even during prolonged usage. You can change the blade tip according to usage. 

Includes 1 angular blade (double ground), L-shaped wrench for changing blades, and main body.
