<p>A hand tool for cutting, such as a pair of pruners, 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 pivotable joint unites the midportions for scissor-like movement of the handles and jaws, and a spring biases the handles and jaws to an open position. According to the invention, one of the handles is rotatable. A transmission mechanism is provided to interconvert the rotation force applied to the rotatable handle into a rectilinear force used to draw the handles together. <IMAGE></p> |
