The precision-matched, induction hardened edges of the Knipex 8" Lever Action Mini Bolt Cutters cut soft, hard and piano wire, bolts, screws, rivets and nails. A 20-to-1 compound joint ratio means that the cutting force is about 20 times higher than the handforce applied. An ergonomically optimized handle shape allows a firm and comfortable grip for the hand. Several different versions of this tool are available including models with a unique cutting jaw recess, spring-assisted handles, straight or angled cutting head designs and a two-component handle grip finish.
