tool
Pinching-iron punch
Leather workers such as the saddler use this hand tool to cut decorative
shapes from the leather. It is a steel chisel (approx. 10-15 cm long)
without handle with a serrated or corrugated blade that can be flat and
flared, semicircular or circular (cf. the punch). The cutting chisel is
placed on the leather and hit with a hammer; the desired shape is cut into
the leather. [MOT]
