Opening and closing the handles of combination pliers opens and closes the jaws Combination pliers are two levers which pivot across each other, like scissors. They are operated with one hand. When the handles of combination pliers are pushed together the jaws come together, so they can grip or cut. Opening the handles opens the jaws again.
Pliers exert the greatest force from the jaws nearest to the pivot point, this is usually where the cutter is positioned on combination pliers The long handles balanced against the shorter jaws means they amplify the pressure applied to the handles, so a greater pressure is produced by the jaws. The greatest pressure is produced nearest the pivot point, which is why the cutter is positioned there.
Wonkee Donkee says: "Pliers are two first-class levers working together. The amplified force the levers produce is called the mechanical advantage.The more mechanical advantage pliers have the more force they produce from the same effort."
Compound action combination pliers have extra leverage for more heavy duty use For additional leverage, there are compound action pliers, which have two pairs of levers attached to each other. These have two pivot points and extra linkage, producing more force from the same effort. You can also get high leverage pliers, which simply have longer handles.
