The New Silvern Carving Knives are made with 01 tool steel and hardened to a Rockwell hardness between 60-62. The beautiful oval shaped walnut handles are comfortable for most carvers but could easily be modified to fit your hands. The blades are about 1/16" thick and "carving sharp" right out of the package. Handles are about 5" long. Each knife is custom made and will vary a little in blade and handle shape.
