This RH-1 Insert is the narrowest cross peen insert.  Used for delicate texturing and fluting tasks.   Fretz RH inserts are designed for chasing and repoussé with either the Fretz RH Holder or the Fretz MKR-7-7 Hammer.  You can use the RH inserts in progression, starting with the broadest inserts to make general shapes quickly, then moving to smaller and smaller inserts to refine them. All the Fretz RH inserts are also available as a set and are included with the Fretz MKR-7-7 Hammer, and the Fretz RH Holder Deluxe Set. Made in Vietnam.
