Key Features
Three Core Electrical ToolsThe set gives you the three hand tools electricians reach for constantly: a forged wire stripper, high leverage lineman’s pliers, and a high leverage diagonal cutter. That means less piecing together a kit and more getting straight to work. High Leverage CuttingThe lineman’s pliers are built to cut with 50% less effort than conventional combination pliers, and the diagonal cutter is designed for hardened steel. Less hand fatigue matters when you’re making repeated cuts all day. Built the Knipex WayForged construction, oil-hardened steel, and polished working surfaces make this Knipex 9K 00 80 158 US 3-Piece Electrical Set a serious jobsite hand tool set, not a throw-in starter kit.
Overview
The Knipex 9K 00 80 158 US 3-Piece Electrical Set is a three-tool hand tool kit built for electricians and anyone doing regular wire work, cutting, and gripping. This is a pliers set designed for electrical work. Model Number: 9K 00 80 158 US. If you want a compact set that covers stripping, twisting, gripping, and cutting without filling your bag with duplicates, this kit makes sense right away.
What makes this set useful is that each tool has a clear job. The 8 inch forged wire stripper handles 10 to 20 AWG solid and stranded wire, includes locating ridges to help find the stripping holes quickly, and cuts 6-32 and 8-32 screws without damaging the threads. That is the kind of detail that saves time at the panel, in a box, or overhead when you do not want to switch between tools just to prep conductors and trim screws cleanly.
The 9 1/2 inch high leverage lineman’s pliers are built for heavy everyday use. Knipex calls out a high leverage design that requires 50% less effort than conventional combination pliers, along with a cross-hatched knurled gripping zone in the jaws for strong pulling and gripping. In practical terms, that means better bite on wire and cable, less hand strain during repetitive cuts, and more confidence when you’re twisting, pulling, or working stubborn material.
The 10 inch high leverage diagonal cutter rounds out the set with serious cutting capability. It is designed to cut hardened steel and is built for smooth operation from the start with no break-in period needed. If your day includes cutting hard wire, trimming fasteners, or making repeated clean cuts where cheaper cutters start to fight you, this is the tool in the set that earns its keep fast.
Material and build quality are where this kit separates itself from bargain pliers sets. The tools use forged, oil-hardened steel, including chrome vanadium heavy-duty steel and vanadium steel depending on the tool. The surfaces are polished, with some black atramentized finish called out in the product data, and the handles use non-slip plastic or plastic coating for a straightforward, durable grip. Nothing fancy here, which is a good thing. These are built to work, wipe down, and go back in the pouch.
On the job, that matters because electrical hand tools need to feel predictable. The forged-on axle on the lineman’s pliers adds strength where cheaper tools usually loosen up first. The beveled cutting edges and flat jaw style support the kind of general gripping and cutting electricians do every day, from branch circuit work to trim-out to service calls. This is not a 1000 volt insulated set, so it is meant for users who know when non-insulated hand tools are appropriate and are buying for mechanical performance first.
The set is also practical from a kit-building standpoint. Instead of buying separate stripping, gripping, and cutting tools one at a time, you get a coordinated Knipex electrical hand tool set made in Germany and aimed squarely at professional electrical work. At about 2.64 lbs, it is substantial enough to feel like real tools but still easy to toss into a service bag, gang box, or drawer.
Who should buy it? Electricians first. It also fits maintenance techs, HVAC installers doing control wiring, low-voltage pros, and serious DIY users who are tired of replacing mediocre hand tools. If your work regularly includes stripping 10 to 20 AWG wire, cutting screws, gripping conductors, and cutting hard wire with less effort, this set covers those jobs with better fit and finish than most off-the-shelf kits.
One Set, Three Daily Drivers
This kit covers the core hand-tool jobs in electrical work without padding the set with filler pieces. You get a dedicated stripper, a lineman’s pliers for gripping and twisting, and a diagonal cutter for clean cuts on tougher wire.
- Includes an 8 inch forged wire stripper, 9 1/2 inch high leverage lineman’s pliers, and 10 inch high leverage diagonal cutter
- Built specifically around common electrician tasks instead of general household use
Grip and Cut with Less Effort
The lineman’s pliers are the muscle in this set. High leverage geometry and a knurled gripping zone help you hold, pull, and cut with more control and less hand fatigue during repetitive work.
- High leverage design requires 50% less effort compared to conventional combination pliers
- Cross-hatched gripping zone helps hold wire and cable securely during pulls and twists
Made for Real Electrical Prep Work
This set is built around common electrical prep tasks, not just general gripping. The wire stripper handles conductor prep and screw shearing, while the cutters are built to deal with harder material when cheaper pliers start to struggle.
- Wire stripper handles 10 to 20 AWG solid and stranded wire
- Diagonal cutter is designed to cut hardened steel and run smoothly right away

Pro Tip
Use the forged wire stripper for conductor prep and screw shearing first, then keep the lineman’s pliers for twisting and pulling. That keeps the jaws on your lineman’s pliers focused on grip work and helps the set stay sharper where it counts.
