Abstract
A hand tool for cutting, such as a pair of snips, includes a pair of opposed elongated members, each member comprising a jaw at a front end portion thereof, a handle at a rear end portion thereof, and a midportion where the members cross over each other. A pivot unites the midportions for scissor-like movement of the handles and jaws about the pivot, and a spring biases the handles and jaws to an open position. A releasable locking mechanism is provided to secure the handles and jaws in a closed position. According to the invention, at least one of the members includes a metal plate having a forwardly extending blade which comprises one of the jaws and a rearwardly extending tang. The handles, pivot and locking mechanism are each made of a moldable material molded onto the metal plate, such that one of the handles is molded onto the tang of the metal plate, and the pivot extends through a central hole in the metal plate. The moldable material is most preferably a plastic, but other moldable substances could be employed.
