ABSTRACT:
A cutting device, particularly a bolt cutting device, is formed of two cutting blades pivoted around two fixed pins held by two side plates and actuated by two lever arms respectively pivoting around two other fixed pins on the same side plates. Pivot elements connect front ends of said lever arms with rear ends of said cutting blades. In one embodiment there are four pivot elements, two connecting each blade with the respective lever arm. Cross members of the same thickness as the pivot elements connect the two pivot pins on which the cutting blades are pivoted thereby permitting the use of thinner side walls. In another embodiment the rear end of each cutting blade and the front end of each lever arm is slotted to receive the respective pivot element, connection being made by pivot pins through aligned holes in the pivot elements and slotted ends of the cutting blades and lever arms.
