Choose a Slitting & Splicing Knife for Your Cable Work

The right knife depends on the cable-preparation task, the blade shape needed for the cut, and whether work is performed on or near energized parts. Compare insulated cable stripping knives, straight-blade splicer’s knives, and curved cable jointer’s knives based on the job at hand.

Use Cases

Prepare cable with controlled cutting

These knives support cable sheath removal, wire stripping, jacket removal, insulation cutting, cable joining, and coring work. They are intended for electrical, telecommunications, maintenance, and utility tasks.

How to Choose

Match blade profile and insulation needs

Choose a straight blade for straight cuts when removing jackets and insulation. Choose a curved fixed blade for cable joining and coring work. For work on or near energized parts, compare the available 1000V-rated insulated options.

Applications

Support electrical and communications work

Representative uses include electrical wire preparation, telecommunications cable work, fiber optic strand work, copper wire preparation, maintenance tasks, and utility electrical work.

Planning Guide

Plan the right fit before choosing

Start with the task

Select the knife style that fits the cut

Different cable-preparation jobs call for different blade profiles and functions. A combined stripping knife can handle sheath removal and wire stripping in one hand tool. A straight-blade splicer’s knife is suited to controlled, straight cuts for removing jackets and insulation. A curved fixed-blade jointer’s knife is suited to cable joining and coring work.

  • Combined stripping functions for sheath removal and wire stripping
  • Straight blade for jacket and insulation removal
  • Curved fixed blade for joining and coring tasks
Consider electrical work

Compare 1000V-rated insulated options

For utility electrical, telecommunications, and related cable work performed on or near energized parts, the available insulated knife options carry a 1000V rating. One is described for work on or near live parts at nominal voltages up to 1,000V and includes a wide insulated grip.

  • 1000V-rated insulated cable stripping knife
  • 1000V-rated insulated cable jointer’s knife
  • Wide insulated grip on the curved-blade jointer’s knife
Plan for carrying and storage

Choose the protection and access you prefer

Protective storage is represented by a plastic storage sheath, a vinyl sheath, and a reinforced leather belt pouch. The belt pouch keeps a straight-blade knife accessible while helping protect it during transport; its steel-riveted construction adds durability.

  • Plastic storage sheath
  • Vinyl blade sheath
  • Reinforced leather belt pouch with steel-riveted construction
