Fretz Michael Good CP-1 Planishing Hammer

Michael Good, in collaboration with Bill and Jordan Fretz, has designed 3 new planishing hammers for use in Anticlastic raising. The Fretz-Michael Good P-1, the Fretz-Michael Good CP-1 and the The Fretz-Michael Good CP-2 are made to Michael Good's specifications by the Fretz hammer & stake factory in Vietnam. Anticlastic raising is a technique of forming metal whereby sheet metal is formed directly with a hammer on a sinusoidal stake. Because most anticlastic raising is done with fairly thin material, Michael Good recommends using these new polished stainless steel hammers with a nylon sinusoidal stake, although they will work just fine with metal sinusoidal stakes or metal stakes and anvils of all kinds.

This is the Fretz-Michael Good CP-1 Cross Pein Planishing Hammer.

The Fretz-Michael Good CP-1 Cross Pein Planishing Hammer has a long and slightly curved head, two design elements that allows for a long arcing stroke, very useful for delivering a predictable strike on the workpiece. The narrow face of the CP-1 hammer is for working on thin concave curves, while the heavier and thicker end gives the hammer a good amount of heft for working on heavier material. Similar to the CP-2 but the CP-1 has different face sizes with a thicker and wider large face and a slightly narrower thin face than the CP-2. Long 250mm (10") long handle length makes this suitable for heavy work when needed.
