(Metal Chasing)

Chokin is a metalworking technique to chase decorations on the surface of a metal using a chisel called Tagane. Chokin techniques, used on Samurai swords and armor, underwent evolution in the 18th century due to the Katakiri-chokoku (half-cut carving) technique which was created to reproduce the brush strokes of Japanese paintings in carved metal form.
