Abstract
A tool useful for clamping, cutting, and the like comprising at least two force multiplying elements which act upon a gear reduction hub that moves a first jaw towards a second jaw. The tool applies greatly multiplied force to the jaws by repeatedly advancing the force multiplying elements in ratcheting manner. The force is maintained in a substantially continuous manner by a separate locking pawl that engages a geared face.
