Combination pliers can have additional features for other jobs As well as coming being available in different sizes, combination pliers can have added features to make them more versatile, or more effective at certain jobs. Some combination pliers include more than one of these added features. Also, many multi-tools will include a pair of combination pliers along with their other implements.

Thumb stops

A lot of combination pliers have hand grips which stop you hands slipping when in use Many combination pliers include thumb stops on the handles. They will usually be made from plastic, being part of the cover over the handles. These small guards are designed to prevent your hands from slipping down the handle when using the pliers. They are particularly relevant on insulated handles, as they stop the user’s hands touching any metal parts which could conduct electricity.

Handle return spring

Some pliers have return springs to make them easier to open with one hand Some pliers incorporate a spring between the handles. This ensures the handles will return to an open position when the pressure is released from them. This makes them easier to use single-handed as they won’t need to be opened manually. There are different designs for return springs: some are hidden within the handles while others are visible.

Locking function

Some combination pliers have a button which will lock them shut Some combination pliers have a button which can be used to lock the jaws shut. This is to protect the surface of the jaws and the cutting blade while they’re not in use.

Compound action

Compound action combination pliers offer more force fro the same amount of effort Combination pliers with compound action can produce more output force from the same amount of input effort compared to standard pliers, without needing to increase their size. They have two double levers, rather than one, which increases their mechanical advantage, so they can be used with tougher materials.

High leverage

High leverage combination pliers should give you more force for the same effort High leverage combination pliers give you extra leverage compared with standard pliers of the same size. High leverage pliers have their pivot point positioned closer to the cutters. This means the handles are extended and the cutters’ output force is increased.

Fish tape pullers

Some combination pliers have a function which allows them to pull fish tape or draw wire Fish tape is also known as draw wire, draw tape, or electrician’s snake. It is used by electricians to pull wires through conduit pipes, heating ducts, and other long, tight spaces where guiding flexible wires would be difficult. Some combination pliers have an extra gripping jaw built into one handle, next to the pivot point. This is positioned to grip the fish tape when the handles are closed.

Nail pullers

Some combination pliers have built in nail pullers Most pliers are not strong enough to be used to remove anything other than fine pins, tacks or staples. Standard nails usually need a more heavy-duty or specialist pair of pliers to remove them. However, some combination pliers include a nail puller grip, specifically designed to remove nails.

Crimpers

Some combination pliers include a crimper for joining wires etc Although not a common feature, some combination pliers have a crimper on the handle side of their pivot point – this is designed specifically for non-insulated electrical crimp terminals. Crimping is a way of joint together pieces of metal, or other ductile materials, by deforming one or more of the pieces. The deformity is usually a small bend or dent and is called a crimp, which is created with a crimper. A common application is jointing electrical wiring.

Insulated handles

Some combination pliers have insulated handles which help protect against electricity Combination pliers designed for use near live electricity will have specially insulated handles. Sometimes insulated pliers are called lineman’s pliers or electrician’s pliers, although, linesman’s pliers are usually more heavy-duty than other combination pliers.
VDE pliers have insulated handles which you know are safe to use with live wires All insulated pliers should be marked as VDE. Tools marked with VDE will have been vigorously tested to ensure they meet the required standards and are safe. This mark will usually be accompanied by the maximum voltage they can be used with – it should be found in the specifications of the tool and be printed on the handle.
Wonkee Donkee says "You shouldn’t use pliers to cut live electrical wires, unless you’re specially trained, VDE pliers usually offer protection for up to 1000 volts, with some able to protect up to 2000 volts."

Bolt cutters

Some combination pliers can be used to cut nails, they usually have a special part which cuts nails and bolts up to a certain size Some combination pliers can be used to cut small screws or bolts. They will have a special place where bolts, up to a certain size, can be inserted to cut them. The specifications should tell you the sizes of bolts which can be cut. They are usually designed to cut the screws used to fix light switches and sockets to the pattress box (the container for the back of an electrical fitting).

Wire strippers

Some combination pliers have additional parts, such as wire strippers Combination pliers designed to be used by electricians or linesmen sometimes include one or more sizes of wire stripper. These are small, rounded cutters which will cut the plastic insulation around a wire to remove it without damaging the wire.

Reaming or deburring mechanisms

Some pliers have a reaming mechanism which allows you to deburr pipes when they've been cut Some combination pliers have serrations on the outside of their jaws so they can be used as a reaming tool for the inside of cut pipes. They can be pushed into the pipe and used as a rounded file to deburr the inner edge.

Offset heads

Some pliers have heads which are offset, angled or bent. This feature is usually used to make it easier to see what you're gripping in some awkward to reach places For reaching some awkward places, there are combination pliers that have angled or offset heads. They allow you to clearly see where the tips of the jaws are when the pliers are being held straight in front of you, where straight handles might mean your hand obscures your view.

Ring spanner

Some combination pliers incorporate a ring spanner in their jaws A hexagonal recess is included on some types of combination pliers to enable use on bolt heads and nuts. The range of bolt sizes that can be accommodated will be limited and will be defined in the products specification.
