Through time the pliers have evolved to having different kinds and different functions. But since its beginnings the commercially available pliers currently did not vary that much from the very first ones. The same concept as that with the first one is still used. A bolt & nut is placed around a third from the tip of the pliers. The moment of arm principle is used to hold the object tighter while applying minimum force to the handles.



As technology continues to develop, more and more variety of pliers have been made to aide every possible need and want. Commonly, these aides are mainly used in machine shops, craft shops, and electrical related jobs. Now pliers have mechanisms that lock and grip the object in place.

The common types of pliers and their uses:

•Flat Nose Pliers. This is the most common type of pliers in the tool shed which is mainly used for gripping objects with great compression loads. Usually flat nose pliers come with a wire cutter that has the same function as a lineman's pliers. The disadvantage of this type of pliers is in gripping objects with slim spaces. There is more of a brute force than finesse.

•Long Nose Pliers. Frequently used in craft production, this type of pliers is essential in bending and shape forming for jewelry making. The downside to this though is that we can't apply force since the shape of this tool is tapered.

•Round Nose Pliers. Also a critical partner in craft making, round nose pliers are used for creating round shaped wires for earrings, necklaces and bracelets. This type of pliers is the same as the long nose pliers, and offers the same disadvantages.

•Crimping Pliers. This particular type has the most variety. Crimping pliers are used to join or seal two things together. The most common uses for these pliers are for industrial use, but they come along with a costly price tag.

•Cutting Pliers. Actually this type of pliers does not belong to the plier's family as stated in its early uses, but the form and concept is basically the same. This type of pliers is used for cutting and stripping wires, which is one of the most useful electrical tools.
