Locking Pliers

Locking pliers, also sometimes called Vise-Grips, vice grips, and Mole wrenches, are a type of plier that offers a strong grip and locking feature. These are technically just another type pf plier, but I thought they deserved their own section because they are unique and very useful when working on motorcycles.

The mechanism that allows locking pliers  to function is the is the over-centre clamp. When the plier handles are closed and the jaws close on an object, the mechanism passes through a point of tightest clamping and as the handle levers are closed further, the jaws release slightly. The pliers maintains a spring pressure on the jaws such that the handle needs to be pulled open to release the clamping pressure. The pliers will  remain clamped on the object without requiring continuous pressure on the handle levers by the user. One side of the handle of locking pliers includes a bolt that is used to adjust the spacing of the jaws, the other side of the handle includes a lever to push the two sides of the handles apart to unlock the pliers. 

Locking pliers are available in many different configurations, such as needle-nose locking pliers, locking wrenches, locking clamps and various shapes to fix metal parts for welding. They also come in many sizes.

Locking pliers offer a hands free solution. Once the locking pliers are locked on, it's not coming off easily. It's like having a set of helping hands around the shop.
