Pliers are another necessity, there are many different varieties made for general or specific purposes. While they can be used to hold objects firmly, they are also useful for bending and compressing a wide range of materials. Pliers have a pair of short metal serrated jaws on one end and longer handles on the other. With a pivot point between the handle and jaws, it creates an advantage allowing the force of a hand grip to be amplified and focused on an object with precision, therefor, you can use them to manipulate objects that you normally can’t with fingers.
Different types of pliers are;
Slip joint pliers can adjust to two sizes, one where the serrated jaws meet when closed, and the other where there is about a 1/4″ gap closed. They are good for holding small to medium objects.
Adjustable pliers, also known as water-pipe pliers or just Channellocks (Channellocks is actually a name brand, but some people refer to all these pliers as Channellocks) are serrated jaws sitting 45 to 60 degrees from the handles. The lower jaw can be moved to a number of positions by sliding along a tracking section under the upper jaw. They can adjust to a number of sizes without the distance in the handle growing wider, as well as often having longer handles for increased leverage.
Diagonal pliers, also known as dikes in the US and snips or side-cutters to other parts of the world, are used for cutting wire and cables.
Lock-jaw pliers, also known as mole grips or the more popular term vice grips (Vice grip and Mole are name brands but the terms are still used as a common name to describe lockjaws) have an adjustable bolt on the longer side used to adjust the spacing of the jaws. The other side has a lever used to push the two sides of the handles apart for releasing the hold. They come in a variety of sizes and jaw styles like needle-nose, clamps, and even wrenches.
Tall and short Needle-nose pliers, also known as long-nose pliers or pinch-nose pliers have long narrow serrated jaws with cutters on the closest to the handle. They are used for holding, bending, re-positioning and/or snipping wire. Their long shape makes them useful for reaching into small areas where cables and/or other materials have become stuck or unreachable with fingers.
