ABSTRACT:
A shearing apparatus includes a pair of scissors including a first blade, a second blade, a first slide on the first blade and a second slide on the second blade. A first handle defines a groove for receiving the first slide, a first portion through which the pair of scissors can be retracted into and extended from the first handle, a second portion, a slot and two apertures in communication with the slot. A second handle is pivotally connected to the first handle. The second handle defines a groove for receiving the second slide. A positioning device is connected to the pair of scissors. The positioning device is normally located in one of the apertures to position the pair of scissors and can be pushed and then moved between the apertures along the slot to move the pair of scissors.
