The Ripper (RS-1) unit is 100% made in the USA and will bolt onto most sets of standard 7 1/4” trauma shears. Its blades, made from 440A surgical-grade stainless steel for durability and corrosion-resistance, receive a proprietary treatment to improve cutting ability and edge retention, making them last 5x longer than standard carbon steel blades. Attach to existing shears with a Phillips screwdriver.
