An insulation-stripping tool designed as a hand tool for stripping insulation from a cable has a first insulation-stripping cutter for stripping the insulation transversely to a longitudinal direction of the cable and a second insulation-stripping cutter for stripping the insulation in the longitudinal direction of the cable.

An electrical wire outer coating splitting device featuring an elongated sleeving element, a nearly as long closed hole space within the sleeving element and having a vertically inclined central axis of symmetry and with the notch portion thereof cut into the outer walling of the sleeving element at a bias relative to the lie of the axis of symmetry and with the notch portion thereof being further amenable to removable receipt and dependable holding of the body portion of a seam ripper element.

A tool for removing of one or more outer layers of a multi-layered jacketed wire includes a base member and a top member pivotally connected to the base member. The scoring tool has a first receiver recess on a first end of the scoring tool. A first cutter extends into a first receiver recess at a distance (d.sub.1) from an interior wall of the first receiver recess, and the first cutter is transversely oriented within the first receiver recess. A second cutter extends into a second receiver recess at a distance (d.sub.1) from an interior wall of the second receiver recess, and the second cutter is longitudinally oriented within the second receiver recess.

An electric spinning pliers apparatus includes a housing, a plier head coupled to a rotatable shaft, and a head-operating handle. The housing may have a wire sleeve stripper, an iris door, one or more controls, and an indicator light. The electric spinning pliers apparatus utilizes the wire sleeve stripper to cut an outer sleeve of a group of wires, exposing individual wires. Each individual wire may be stripped by the iris door, while the plier head may grasp and rotate, via a motor, each of the individual wires into a single unit. The plier head may then twist a wire nut on the twisted wires.

The multifunctional combined cable stripper includes a first clamp body and a second clamp body, which are hingedly connected through a hinge shaft. The hinge shaft is connected to a rotating disc through a loosening-tightening device, and the rotating disc is disposed with circularly arranged threading holes with different opening sizes. The first clamp body and the second clamp body are respectively defined with two arc-shaped grooves on adjacent sides of the first clamp body and the second clamp body, and the two arc-shaped grooves are pieced together to form a circular hole corresponding to the threading holes. A bottom of the arc-shaped groove of the second clamp body is embedded with a blade, and a cutting edge of the blade faces towards the hinge shaft and is arranged in the circular hole formed by the two arc-shaped grooves and further switchably located in any one of the threading holes.
