Made in Miki City, Japan by master blacksmith Ioroi. These chisels have a blade length of approximately 62mm(2.1/2") and longer shoulders and tangs. The overall length is approximately 230mm(9"). They are well balanced and will take a blow from a hammer for heavier work as well as taking the thinnest of paring cuts for fine work. These professional grade chisels are forged using high carbon steel (Shirogami White Paper #2 steel) laminated to a softer low carbon backing steel. They are hardened to over HRC 65 and will hold a razor edge for far longer than an equivalent western chisel. They feature red oak handles, fitted with steel hoops finished with a mushroomed top ready to go. This set comprises the four most popular sizes: 6mm, 12mm, 18mm and 24mm.
