GrooveTech Diagonal Cutters
While developed for guitar and bass strings that are made of hardened stainless steel or nickel, these cutters also work great in aviation. Ordinary diagonal cutters are designed for soft copper, and thus fail miserably when used on harder metals. GrooveTech Cutters use a proprietary heat-treatment process for confident cuts. Their compact six-inch length and vinyl grips feel great in your hands.
