  • Patent number: 5092049
    Abstract: Disclosed is a device for cutting cloth or the like, including a lower substantially fixed blade and an upper movable blade pivotal with respect to the fixed blade. A handle extends at an acute angle with respect to the fixed blade and substantially transverse to the pivot axis of the blades. A lever is pivotally disposed within the handle, and the lever contacts a cam attached to the movable blade such that pivoting the lever effects pivoting of the movable blade. A trigger mechanism is disposed in the handle and manipulation of the trigger mechanism effects pivoting of the lever, and thus the movable blade.
