The SUSA 'genno' is a brass plated hammer with a steel core, to absorb some recoil shock during use. It weighs 300g and the head has eight edges to help with work in tight spaces. The head also has one flat and one convex striking area, depending on the work required - tapping chisels, or setting nails.
