Both end cutting and carpenter’s pincers consist of two levers working in opposite directions, like scissors, around a central pivot. Force placed on the handles by pushing them together is multiplied several times by a pivot point, or fulcrum, and channelled through the jaws. This lets you apply a lot more leverage than using your bare hands.
Pincers with two pivot points let you apply even more leverage, as they work alongside each other to amplify your cutting power.
The first pivot point acts as a lever on the second one, magnifying the force applied to the jaws for the same amount of effort.
The jaws of end cutting pincers are extremely sharp. Good quality ones will meet together without any gaps, giving plenty of cutting strength. And because the heads are almost flat, you can cut flush with the surface of the workpiece.
The jaws are also designed to act as clamps, holding pieces of wire in place so you can twist them.
Because the head of carpenter’s pincers is rounded, you can use it as a point of leverage by rolling it to pull out nails.
