Simple Job-Site Method for Stripping Electrical Wire (Knife Only)

Learn how to strip electrical wire safely using just a contractor knife. Step-by-step method shown by a professional junk removal and clean-out contractor in Pierce County, Washington.

In this video, I show how to strip electrical wire using only a contractor knife. I hold the wire steady with my left hand, lightly score the outer jacket with the knife in my right hand, and then pull the wire through so the casing slides off cleanly. This is a simple job-site method that doesn’t require any special tools.

How to Strip Wire Using a Contractor Knife (Step-by-Step)

Step 1: Hold the Wire Steady

Grip the wire firmly with your left hand, keeping it steady and straight. Make sure your hand is positioned safely behind where you’ll be cutting.

Step 2: Lightly Score the Outer Jacket

With your right hand, place the contractor knife blade gently into the outer casing of the wire.
You are scoring, not cutting through — apply light pressure.

Step 3: Pull the Wire Through the Blade

Keep the blade position steady while pulling the wire forward with your left hand.
As the wire slides, the outer jacket splits cleanly.

Step 4: Remove the Casing

Once the jacket separates, pull it off by hand to expose the clean copper inside.

Always use caution when working with sharp tools. Cut away from your body and wear gloves when appropriate.

Safety Tip (Important)

  • Always cut away from your hand

  • Use controlled pressure — never force the blade

  • Wear gloves if the wire is stiff or dirty

This method is fast, efficient, and commonly used during clean-outs and demolition work.
