An improvement in a punch design for a punch used within a strapping tool which creates seal-less connections between overlapping steel strap segment s that are to be bound together. The punch is relieved along the edge surfaces that experience extreme forces during the stamping operation which physically binds t he strap segments together. The relieved edges also provide a less acute angle for the stamped edge surfaces to scrape against once the tension on the straps is releas ed.
