Ordinary diagonal cutters are designed for copper wire, which is soft and easy to cut. However, guitar and bass strings are made of hardened stainless steel or nickel with thicknesses approaching 3mm. CruzTOOLS developed the GrooveTech String Cutters specifically for Guitar and Bass strings. A special induction heat-treatment process prevents blades from denting, and the high-leverage handle design makes even B bass strings easy to cut. Comfortable rubber grips feel good in your hands, and the cutters are compact enough to fit into any guitar case or gig bag. Designed to easily cut guitar and bass strings. Unlike ordinary cutters, blades wont dent. Compact, yet powerful. Comfortable grips.
