Engineering: The tool body is made from aircraft quality 6061 billet (block) aluminum. Internal hardware is made of a durable corrosion-resistant 303 stainless steel for salt and fresh water use.
Design: The unique patented design of the cutter-head provides a reducing-triangle cutting action which prevents braided lines, mono, and stranded cable from fraying. This keeps the line and cable intact and allows an easy and sure fit into a cable crimp. It does not leave any strands sticking out to cause injury to your hands.
