Dual Striking Faces with Distinct Shapes


This hammer features two striking faces: one flat and the other slightly curved.


A traditional genno hammer that performs well in various situations, with a design especially effective for nail driving.

By driving the nail on a flat surface at the beginning and then on a curved surface at the end, you can avoid scratching the material surface.
