The MKR-4 has two ball-shaped faces of different sizes for doming and stretching metal and to create interesting, dimpled textures. This hammer is part of the Fretz Maker series which was designed to deliver quality hammers at a more affordable price point with handles made from American ash. Fretz casts all their hammer heads from 420 stainless steel and tool hardens them to 50 HRC. Made in Vietnam.
