The Jim Blurton clipping punch is designed to set clips. It is made from S7 tool steel, an air hardened tool steel which is easily maintained.
The clipping punch offers the best performance when it is maintained well. It is recommended that sharpening of the clipping punch is done at normal forging temperatures and allowed to air cool. The clipping punch should ideally be placed on the side of the forge whilst cooling. It is not recommended that the clipping punch is placed on a cold surface as sudden cooling may cause stress fractures. Any burrs that may occur on the head should be regularly ground back.
The clipping punch was developed and tested at Jim’s forge in Mid Wales.
