How to Use Electrician Scissors | Cut & Strip Wire Safely

Electrician scissors look like heavy-duty shears, but they do more than cut. A good pair strips insulation, scrapes wire clean, and slices through cable and tape without mangling the conductor inside. The technique matters as much as the tool — the wrong grip or the wrong notch turns a simple job into a nicked wire or a cut finger. Here’s the proper way to hold and use them, plus the safety limits every model shares.

How Do You Hold Electrician Scissors Correctly?

Your grip is the difference between clean cuts and dangerous slips. Klein Tools, a leading manufacturer, instructs users to keep fingers behind the curved guard and place the thumb on the multi-grooved thumb-rest indentation — never in front of it. That guard exists to stop your hand from sliding toward the blade when you apply pressure.

For most models:

• Wrap your fingers through the larger handle loop, behind the guard.
• Rest your thumb on the flat thumb-rest area, not inside the loop.
• Keep your other hand clear of the blade path entirely.

The grip keeps your digits behind the cutting edge even if the scissors slip or the wire snaps free. Bessey adds that you should always cut away from your head and body, and store the tool with the cutting edges closed when not in use.

How to Cut and Strip Wire With Electrician Scissors

Cutting and stripping use two different parts of the blade. For cutting, place the wire deep into the scissor blades near the pivot — that’s where the leverage is strongest. Squeeze with controlled pressure; don’t yank or twist. A clean cut needs one firm squeeze, not sawing motion.

Stripping insulation is where electrician scissors earn their keep. The blades have notched grooves sized for specific wire gauges. The general technique, per manufacturer guidance:

1. Close the groove over the insulation at the point you want to strip.
2. Rotate the scissors once fully around the wire to score the insulation evenly.
3. Pull the insulation off with the wire held firmly in your other hand.

The rotating step is what prevents nicking the copper underneath. Skip it and you’ll likely cut into the conductor, which weakens the wire and can cause failure later. Different models carry different notch sizes — one common configuration handles AWG 16, 14, and 12 wire, while another source lists grooves for 19- and 23-gauge wire. Check your model’s marking to match the notch to your wire.

What Are Electrician Scissors Rated For? Safety Limits

Not every pair of electrician scissors is rated for live work, and that distinction matters. Standard electrician scissors are for de-energized circuits only — you cut wire that’s disconnected from power. If you need to work near live equipment, you need an insulated model with a specific rating.

That’s a very different tool from a standard pair. Bessey’s guidance is blunt: disconnect power when working on electrical equipment, and always wear safety goggles and gloves.

Common mistakes that damage both tool and wire:

• Cutting live conductors with a non-insulated tool
• Using excessive force — let the blade do the work
• Cutting oversized or hard materials like nails, screws, or steel strapping
• Holding fingers in front of the guard

Electrician scissors are designed for wire, cable, tape, and light sheet materials. Bessey explicitly states that manual sheet-metal snips are not suitable for round or rectangular metal shapes such as wires — and the reverse is also true. Don’t press electrician scissors into service as general metal cutters.

Choosing the Right Pair

When you’re ready to buy, look for features that match how you’ll use them. Spring mechanisms reduce hand fatigue on repetitive cuts. A one-touch safety lock keeps the blades closed in a pouch. Nickel-plated blades resist corrosion, and dipped handles improve grip. For live electrical work, the VDE/IEC 60900 certification is non-negotiable — that’s the only thing that tells you the insulation is genuinely rated for voltage.
