Lineman's pliers (US English), Kleins (generic trademark, US usage), linesman pliers (Canadian English) and combination pliers (UK / US English), or simply pliers (since other versions are more commonly disambiguated with a prefix, such as "needle-nose", etc) are a type of pliers used by linemen, electrical contractors and other tradesmen primarily for gripping, twisting, bending and cutting wire, cable and small metalwork components. They owe their effectiveness to their plier design, which multiplies force through leverage.
Lineman's pliers are distinguished by a flat gripping surface at their snub nose. Combination pliers have a shorter flat surface plus a concave / curved gripping surface which is useful in light engineering to work with metal bar, etc. Both usually have a beveled cutting edge similar to that on Diagonal pliers in their craw, and each may include an additional gripping, crimping, or wire shearing (for a flat ended cut) device at the crux of the handle side of the pliers' joint.
Atramentizing is a corrosion protection process in which steel is coated with phosphate using a zinc phosphate solution at 90° C (194° F).

Advantages:
- Handy use when working in confined areas thanks to slim head design and pointed jaws (anti-twist)
- Gripping surfaces with special convex contour on one side for secure gripping of flat parts
- Milled groove in the gripping area permits small parts such as nails, pins and bolts to be held and pulled
- The reliable and diverse combination pliers when out and about
- Easy cutting thanks to the high leverage joint
- With cutting edges for soft, medium-hard and hard wire
- Long service life and stable tips
- Forged from special high grade tool steel, manifold oil-hardened
- Milled groove in the gripping area
- firm grip also on flat material due to three-point rest
- tip keeps its shape even during greater torsional forces
