Abstract
A pliers-type cutting hand tool utilizes a pair of elongated members pivotally connected adjacent their upper ends, the lower portions of said members form a pair of elongated handles. One of the members on its upper end is provided with a clamp, where an object may be secured, the other member carries a changeable saw blade, due to oscillating movement of which the cutting process is performed. The pivot connection of said members is capable of step-by-step movement towards the clamp, the constant engagement of the saw blade with the object being cut is thus provided.

A pliers-type cutting hand tool, comprising:
- a pair of pivotally connected elongated members, each having an upper, mid-, and lower portions respectively;
- one of said elongated members being stationary and provided with a clamp, positioned on the upper portion thereof, said clamp being used for securing an object being cut, the midportion of said stationary member being of elongated cylindrical shape and having a threaded section thereon, and the lower portion of said stationary member forming a stationary handle;
- the other of said elongated members being laterally movable and carrying a segmental saw blade positioned on the upper portion thereof, said blade being used for cutting an object secured in said clamp, the lower portion of said laterally movable member forming a movable handle positioned at a suitable distance from said stationary handle;
- a bracket carrying a pivot pin, whereupon said movable member is pivotally mounted;
- a sleeve, incorporated with said bracket and slidably disposed on the midportion of said stationary member;
- a nut, supporting said sleeve and rotatably mounted on said threaded section, said nut, when rotated, being capable of moving translationally on said stationary member and imparting translational movement to said sleeve and said bracket towards and away from said clamp.
