This hammer is ideal for adjusting Japanese planes and striking chisels. It is made by Susa and has an octagonal head. This hammer is perfectly flat on the sides of its head and can be used sideways as well for a larger surface area. E.g. adjusting a joint without damaging the work surface.
Because the head is made of solid copper and therefore, being a non-ferrous metal, it can be used to strike metal without any sparking occurring.
