This is a Mike Shipley knife  ( formally Dennys ) this is a 1-1/4 inch length blade.  01 Tool steel with a RC-59 Rockwell.. holds edge very nicely and is used in the carving circle amongst the pros..These make a great Christmas gift for the carver. come in plastic tube for protection. One of the finest knives that can be added  to the carvers kit.  I am thrilled that Mike and his lovely wife are continuing to make these exceptional knives for the carvers and puts all his experience in making carving fun again.  Flat blade knives are just cutting butter on basswood.
