The UP-B240 Shark can cut 100-pair telephone cable, 4/0 aluminum and 2/0 copper. This is the best high leverage cutter. The special grinding and blade design cannot be found in any other tool. There are other tools available in the market but if you actually compare cut for cut the Shark has no competition. Made in the USA from forged tool steel with a specially honed cutting blade that is designed like no other, ask for The Shark by Benner-Nawman®.
