One prong diamond stitching chisel.
Use the one prong chisel for going around corners. Made from chromoly 41xx steel giving an excellent strength to weight ratio, this chisel is stronger and harder than standard steel and the black coating prevents corrosion and provides wear resistance.
For best results use a good quality cutting mat underneath and hit with a wood or poly mallet.
To preserve the life of a chisel further push into a beeswax block prior to use.
The stitching chisels are diamond tipped to give the traditional slant for hand stitching and come in a choice of sizes to give different stitch lengths.
