Our 3/8˝ (9mm) Chisel is designed for finish and paring cuts and yet is strong enough for light hammer work. Traditionally, woodworkers use them to trim intricate joints to finished dimension. The blacksmith hand forges the blade from a lamination of hard high carbon steel and soft wrought iron material. Each tool is heat treated to Rockwell hardness c63 - c64. The handle is hand-turned from Japanese White Oak. Each chisel comes fully sharpened and polished, with instructions for maintaining a razor edge. The blade length is 3½˝ and overall length is 13½˝.
