The 8 Best Automatic Wire Strippers of 2026

The IRWIN strips like the Klein — squeeze, grip, pull — and then keeps working: the same head carries crimping nests for 10 to 22 AWG insulated and non-insulated terminals and for 7 to 9 mm ignition terminals. A swivel knob micro-adjusts the jaws for gauges below 20 AWG, and a sliding stopper sets how much insulation comes off.

That combination is why it stays in the bag for mixed work. Wiring a trailer plug or a run of connectors means stripping, crimping, and trimming inside the same minute, and reaching for one tool instead of three is a convenience you notice at the end of a job rather than the start. The stopper is the part we came to rely on most: set it once and every strip in the run comes out the same length, which matters when the wires land in a terminal block.

It's a self-adjusting wire stripper rather than a precision one. On soft insulation the jaws can stretch the sleeve instead of releasing it, and the pull runs short unless you back the stopper out and check the first strip of a run. For terminal work, where a quarter inch of copper is all you need, neither matters. For long pigtails in a panel, it's the slower tool.

NM-B cable is the reason this tool exists. The 11061 has a dedicated slot for sheathed Romex, so you clamp the cable, squeeze, and the jacket comes away in one piece instead of a knife blade traveling down the conductors — the step where most cable damage happens.

Past the jacket it strips 10 to 20 AWG solid and 12 to 22 AWG stranded, with a tension dial that softens or sharpens the bite for different insulation and a length stopper for repeat strips. The cutter at the nose takes up to 8 AWG solid, so it does the same trimming work as the Katapult.

The fussy part is individual conductors pulled out of the jacket. The jaws are happiest with sheathed cable and clean single sizes, and thin, slick insulation sometimes needs a second squeeze before it lets go. Set the tension dial too tight and the blades score copper; too loose and they skate over the sleeve. Neither is a dealbreaker in a house full of 12/2 and 14/2, where you calibrate once and leave it.

Where that leaves it: this is the Klein that goes to a panel or a remodel, and the Katapult is the one that goes on a bench full of loose wire. If your work is mostly sheathed cable — outlets, switches, a subpanel — the trade runs the other way and this is the one to buy.

At 7.09 inches and 151 grams, the Knipex is the tool that fits where plier-style strippers don't. The head is narrow enough to open inside a crowded device box, and the body is light enough that holding it overhead in a ceiling box isn't a chore.

What we like most is that the automatic adjustment covers 0.2 to 6 mm² — roughly 24 to 10 AWG — without a dial, so the same jaws handle a 24 AWG control lead and a 10 AWG feed in the same session. The length stop holds its setting between wires, and the whole tool is short enough to keep in a pocket while you're up a ladder.

If your stripping happens inside boxes and cabinets, the reach is worth paying for; if it happens at a bench, the Klein gets you there for less. It's a stripper and nothing else, so buy it for the shape and the mechanism rather than a toolbox's worth of functions.

Fine wire is where the Jokari earns its slot. The jaws close down to 0.2 mm², finer than most of the strippers here will touch, and the plier-style handle locks shut, so it rides in a shirt pocket without snagging on anything else in there.

It works like the rest of them: squeeze, the jaws grip and score, and pulling the tool away takes the insulation with it. The length stop adjusts for repeat work, and Jokari sells spare blades, which matters on a light tool — the cutting edges are what wear, and a stripper you can re-blade is one you keep.

Against the Knipex, which covers the same 0.2 to 6 mm² spread, the Jokari is lighter at 90 grams and carries a small cutter in the head. The Knipex is the better shape for reaching deep into a box. Where the Jokari wins is the wire you can barely see: thermostat leads, LED pigtails, and bench work where the whole run is 22 to 24 AWG.

This is the least expensive tool we recommend, and the smallest: a 6.89-inch body with an eagle nose that tapers to reach into a backbox or the shell of a connector. It strips and cuts 14 to 24 AWG solid or stranded, which covers lamp cord, speaker wire, and most low-voltage work around a house.

The action is spring-loaded rather than the plier-style squeeze of the bigger picks — press the handles, the jaws grip and pull, and a pressure knob adjusts how hard the blades bite. That knob is the feature worth having at this size: soft silicone insulation and stiff PVC want different amounts of bite, and without an adjustment you're guessing at both.

It's a two-function tool. There's no crimper, so terminals stay a separate job, and the frame is polypropylene rather than cast metal. For the occasional strip, that's the right amount of tool, and the light body is part of why it's pleasant to use on a small job.

We treat it as the household drawer tool rather than a bag tool, and that's the honest summary: it's the one you buy for the job in front of you, not for the rewiring you might start next spring.

The WEICON No. 5 is the certified one: TÜV and GS marked, made in Germany, with blades cut from Solingen knife steel and a body of glass-fiber-reinforced polyamide. It strips 0.2 to 6 mm² automatically and carries a side cutter in the head for cable up to 2 mm in diameter.

Two details stand out. The length stop runs from 5 to 12 mm, which covers terminal work without moving the tool, and at 4.8 ounces the stripper is light enough that one-handed work from a ladder doesn't wear out your forearm. The side cutter earns its place too — trimming small cable without a reach for the diagonal cutters keeps a run moving.

Where it lands: the same 0.2 to 6 mm² coverage as the Knipex, a friendlier price, and a longer body, which is the difference that matters. On a bench or in front of a panel with room to work, the WEICON is the sensible buy. Inside a packed device box, the shorter Knipex is worth the extra.

This is a pair, not a single tool: an automatic stripper rated 24 to 10 AWG and a ratcheting crimper rated 26 to 10 AWG for heat-shrink connectors. Each tool has its own gauge controls and pressure adjustment, and the crimper has a quick release for a crimp that starts to go wrong.

The stripper is a familiar self-adjusting design with a dial for the bite, and it handles the wire sizes a vehicle actually uses. The crimper is the reason to buy the kit: ratcheting action, dies across the heat-shrink range, and a body that feels more substantial than the money suggests.

What to watch: the ratchet can stick mid-crimp and needs the release worked, and crimp quality tracks the terminal as much as the tool, so wires pull out of some brands of connector and hold hard in others. Run a handful of scrap terminals through it before you commit a harness. When the terminal matches the die, the result looks like a shop crimp.
