Ergonomic plier

A tool, comprising:

• a body defining a cavity and including a handle portion;
• a lever hingedly fixed to the body and including a piston engaging portion and a trigger portion, wherein the piston engaging portion is disposed within the cavity, and wherein the lever is movable between a first position wherein the trigger portion is distal from the handle portion and the piston engaging portion is proximal to the handle portion, and a second position wherein the trigger portion is proximal to the handle portion and the piston engaging portion is distal to the handle portion;
• a head cylinder at least partially disposed within the cavity having a body engaging portion and a jaw receiving portion, wherein the body engaging portion further defines a piston cavity that opens into the jaw receiving portion;
• a piston disposed within the piston cavity and including a lever engaging portion and a jaw engaging portion, and wherein said piston is movable between a retracted position, wherein the piston does not extend into the jaw receiving portion, and an advanced position, wherein the piston extends into the jaw receiving portion;
• a jaw assembly disposed in the jaw receiving portion and comprising a first jaw and second jaw rotatable coupled to one another at a fulcrum, and wherein each of the first and second jaws include a working portion and a piston engaging portion, and wherein the jaw assembly is movable between an open position, wherein the respective working portions are spaced apart from one another and the piston engaging portions are adjacent one another, and a closed position, wherein the respective working portions are adjacent one another and the piston engaging portions are spaced apart;
• and characterised in that the head cylinder is freely rotatable within the cavity and further characterised in that the piston engaging portion of the lever is in communication with the lever engaging portion of the piston, and the jaw engaging portion of the piston is in communication with the piston engaging portions of the jaws, such that when the lever is moved from the lever's first position to the lever's second position, the piston is moved from the piston's retracted position to the piston's advanced position, and the jaw assembly is moved from the jaw assembly's open position to the law assembly's closed position.
