Best manual wire strippers

Manual wire strippers are an older technology for stripping insulated wire. Surprisingly, these simple wire strippers are still the most widely used wire stripping tools to date. They have a permanent place in many people’s tool bags and toolboxes.

To electricians, regular wire stripper pliers are an EDC because they are inexpensive, versatile, and easy to carry around. Auto technicians who do car wiring repairs also carry a pair of manual strippers in their toolkits. They are essential for working on car wiring harnesses and a good fallback option for when the auto wire strippers fail.

As a general auto mechanic, I always have my trusty Klien wire stripper pliers with cutters in the belt plier pouch in case I need to wire up or fix some connectors.

There are many brands of manual wire strippers to choose from. But how do you make sure you select the best stripper pliers for your project?

Well, in this article, I share the best manual wire strippers on the market and some of the most important features to look for when shopping for one. You will also find a step-by-step guide on how to use the regular wire strippers to remove insulation and outer cover from electrical wires and cables without damaging the core.

What are manual wire stripper pliers?

Manual/regular wire strippers are one of the two major types of wire stripping pliers. They have notched blades for removing insulation from wires and cables.

Typically, the jaws of manual wire strippers have multiple slots of graduating sizes for stripping wires and cables of different gauges.

When you place an insulated wire in the correct slot and squeeze the handles, the notched cutters cut into the insulation all around the wire. This allows you to pull off the section of the insulation to expose the conductor core for electrical connection.

As I mentioned, manual wire strippers are the most common stripping tool. Virtually anyone who works with electrical wires has a pair. It is the first professional wire stripping tool most junior technicians own after they graduate from using teeth and knives to strip wires.

Regular wire strippers are good for stripping both stranded and single-core wires. You can also use them to take off the jacket of medium-sized multi-conductor cables.

However, because manual wire stripper pliers don’t offer a great mechanical advantage, it is best to use them to strip light gauge wires of 10 – 30 AWG that do not require massive hand strength. They are also great for stripping wires that have a soft insulation cover.

But if you strip hundreds of wires a day or work with multi-conductor cables, you need a decent pair of automatic wire strippers. It will provide better leverage and as a result take away the strain from your hand.

How to remove insulation from wires using manual wire strippers

Stripping wire with regular wire strippers is a straightforward exercise if you have a good tool. In this section, I share the step-by-step process of stripping wire with manual wire stripper pliers.

how to strip wire with manual wire strippers
Put the wire in the right slot and along the slant

1. Identify the size of the wire you want to strip.

You can tell the size or gauge of the wire by checking the value printed on the insulation. Typically, it will be in xx AWG or xx mm2, where xx is the size. For example, you can find 10 AWG

2. Check the capacity of the wire stripper.

After finding the gauge of the wire, see if the wire stripping section has a notch for that size. If it doesn’t, then it means your wire stripper does not have the capacity and now you might need to find another wire stripper.

Typically, the stripping range of a wire stripper will be laser etched on the side of the jaw or printed on the handles. For instance, most regular wire strippers for electrical wires have a stripping range of 10 – 24 AWG. On the other hand, wire strippers for electronic wire have a stripping capacity of 20 – 30 AWG.

3. Place the insulated wire in the right notch on the wire stripper.

If the wire gauge is within the stripping range of the wire stripper, open the jaws and place the wire in the right slot. The correct stripping notch has the same size as the wire. That is, if the wire is 10 AWG solid, you should place it in the notch marked 10 AWG.

Be sure to check if the wire is solid or stranded before placing it in the notch. This is because the stripping notches on manual wire strippers are different for solid and stranded wire.

Actually, most wire strippers have different size labels for the two types of electrical wires. But generally, the same stripping notch will take smaller gauge stranded wire than solid wire. The reason is that stranded wires have thicker insulation and hence a bigger outer diameter than solid core wire.

Also, make sure you place the wire from the appropriate side of the jaws because manual wire strippers are not unidirectional. You should feed the wire on the side where the notch appears to slant upwards. Makes sure the wire slants along with the notch.

4. Close the jaws tightly to cut into the insulation.

First, make you are stripping enough length from the end to avoid stripping back more or less insulation. Once you are sure that it is the correct stripping length, squeeze the handles of the wire strippers together to close the jaws and cut into the insulation.

5. Pull off the insulation.

Hold the wire in one hand and squeeze the handles of the pliers with the other hand. Give the wire strippers a twist to cut the vinyl cover all around. Then pull the wire and the wire strippers in the opposite directions to pull off the insulation and expose the conductors.

6. Inspect the conductor core or strands for damages

Check the conductor core to ensure it is intact without nicks or scratches. If it is stranded wire, make sure no strand is cut. Otherwise, if you notice any damage to the conductor, snip off the bare wire and strip the wire again.

This time around, use the gripper tip or linesman pliers to grip and pull off the insulation. If the damage happens again, use the next bigger notch to strip the wire.

What to do if you don’t know the wire size?

Sometimes the printing on the insulation may not be visible and you may not be able to tell the size of the wire. In such situations, the best thing is to try all the slots starting from the largest until you find a notch that grips better.

If you strip the wire and notice a nick on the strands or a scrape on the solid core wire, select the next bigger notch. The correct stripping slot should not nick the core or sever the wire strands. It should leave the conductor core intact.

Why choose manual wire strippers?

The following are 5 main reasons why you need manual wire strippers.

  1. Manual wire stripping pliers are inexpensive. Typically cost less than $15.
  2. Regular wire strippers cut insulation more cleanly than automatic wire strippers which tear the insulation and leave an irregular edge.
  3. Manual wire strippers do not slip if you select the right stripping slot.
  4. Best for electronic wire and any light gauge wire (16 – 30 AWG). They don’t shear the insulation or break wire strands.
  5. Lightweight and therefore easy to carry around in your toolbelt or pliers holster.
  6. Best for round cables and stranded wires.
  7. Best for people who can correctly tell the size of a wire or for wires whose size is known.
