The MKR-7-7 is built to handle a variety of tasks using 8 replaceable inserts: 7 metal faces for chasing (see below) and 1 nylon flat  face for working metal without leaving any marks. Use the included hex key to change faces. For more nylon faces, this hammer can use the 821-7043 set of 9 inserts created for use with the HMR-7 hammer.  Fretz casts their hammer heads from 420 stainless steel and tool hardens them to 50 HRC. This Maker series delivers quality hammers at a more affordable price point, with handles made from American ash. Made in Vietnam.
