What makes this Japanese Genno Hammer special?

  • The flat face has various woodworking applications while the curved face is meant for flush nail finish without leaving indentations or other hammering marks
  • The curved face can also be used in a Japanese joinery technique where a tenon is hammered slightly (without damaging the fibers with hard edges) to fit snugly within a mortice. Later expanding and locking the joint tight
  • Due to its octagonal shape it’s very handy to use on its side, within harder to reach inner corners and such
  • Tempered faces and softer steel body prevents the head from bouncing off the surface and puts less force on the wrist
