No-Nik fiber optic strippers meet the most stringent specifications. Used properly they are 100% reliable! Plastic heads, which make contact only with the buffer, center and support your work on both sides. Cutting blades made from razor quality steel score the buffer completely. Back-up blades support the cutting blades, nest positively, and lock up when the tool is closed to maintain perfect concentricity. Buffer being removed acts as guide and protection for the fiber. Color-coded handles ensure proper tool selection, quickly and easily.
