Top quality diamond chisels for punching hand-stitching holes. A must for custom work where large quantities of punching is needed. 

After using wing dividers to mark your stitch line, strike this tool with your maul to create 4 holes at a time. When you move your punch down the line, put the first prong back into the last hole punched. This will ensure even spacing as you punch the next three holes.

You may consider pairing this with the single prong diamond chisel for going around corners easily.
