Tested in the rugged fishing grounds off New England and Canadian Maritimes, our Piranha Dual Line Cutters offer superior cutting performance and help protect your boat’s propeller and running gear from catastrophic failure due to entanglement in marine debris, kelp, and other nuisances. These disc-style line cutters feature dual-serrated edges and provide twice the cutting surface area of conventional line cutters offering you redundancy and a prolonged life span. The Piranha line cutter’s split design allows for easy installation (approximately 10 minutes) and is an excellent alternative to "scissor" style line cutters that are less robust, difficult to install, and require more maintenance.
