Master Blacksmith Yoshio Usui from Yoita, Japan, is a fourth-generation chisel maker, starting his apprenticeship with his father at age 15. Since 1962, he has been making chisels one at a time, working alone to perfect his craft. Mr. Usui has developed a shrewd insight into chisel making, using a mixture of handwork and machines. His preference for High-Speed Steel (HSS) provides a more consistent chisel that sharpens easily and stays sharp a long time.
