Used to dome metal from the inside. The metal is stretched from the inside as it is supported on a sand bag or a depression carved in wood. Doming a piece of metal before raising makes it easier to control because the shape becomes rigid.  Face diameters are 15mm (9/16") and 12mm (7/16").  This hammer also leaves a very interesting dimpled texture on flat and slightly domed metal when hammering on the outside of a form against a stake. Fretz Hammers feature beautiful and strong hardwood handles, oil finished and tapering to a slender neck for flexibility. Head is cast from 420-grade stainless steel and hardened to 50HRC for maximum durability. Faces are polished to a mirror shine.  Made in Vietnam. 

Head length: 74mm (just under 3")
