Kunikei Set of 10 Hand Hammered Bench Chisels are made by the Samurai blacksmith Yoshiro Ikeda (see below for family history). To form the blade, he hand forges the best quality Yasuki high carbon white steel to a backing of soft low carbon steel. Like old time chisels, all of the shaping is done with the hammer and the marks are left on the blade. Rather than using a power grinder, Mr. Ikeda hollows the back of the blade using a special hand file called a Soto Sen. This is exacting work, and only one other chisel maker uses this technique. But the benefits are easier sharpening and longer lasting chisels. Each chisel then goes through a rigorous tempering process and is hardened to Rockwell C64-65. Mr. Ikeda personally sharpens each blade to a razor like edge. The handle hoops are hand hammered, and the handles are made from best quality Japanese Red Oak, Hon Akagashi. Sizes include 1/8", 1/4", 3/8", 1/2", 5/8", 3/4", 7/8", 1", 1-1/2", & 2" shipped in a signed wooden box.
