A hand tool or plier including a plurality of lever arms, a number of jaws, a cam assembly and a cam follower. The plier tool provides efficient and comfortable transfer of energy from the human hand to the plier tool by utilizing an lever arm and at least part of the cam to generate a transformational increase in mechanical advantage and allow maximum amount of power to be derived from a hand squeezing action, and to do so with a minimum discomfort and strain to the hand because the strongest part of the hand squeezes the handles portions with the greatest travel.

A cutting apparatus having a ratcheting and non-ratcheting configuration for cutting food. The cutting apparatus includes a pair of handles with a cutting blade having a toothed portion and a non-toothed portion. In the ratcheting configuration, the cutting blade is held in position by a position holder, engaging the toothed portion of the cutting apparatus. In the non-ratcheting configuration, the position holder engages a separate non-toothed portion of the cutting blade. Additionally, in the non-ratcheting configuration, a bottom bar and top mechanism bar allows for the cutting apparatus to be locked into the non-ratcheting configuration.
