One of the faces of this exquisite hammer is randomly ground to impart the texture of "Raw Silk." This face is slightly domed, making it possible to apply a texture to a modulated piece that cannot be passed through a mill. The other face of the hammer is smooth. Like all Fretz tools, the craftsmanship is superb. Each tool has a 420 stainless steel head hardened to 50Rc and polished to a mirror-bright finish. Handles are meticulously fashioned from rosewood, shaped to provide perfect balance and control. Face diameter is 19 mm, and overall length is 9".
