Knipex Strippers & Crimpers
Knipex wire stripper tools make cable prep quicker and cleaner, from flex and data cable to control wiring, without nicking conductors or wasting time on rework.
If you're wiring boards, fitting accessories, or stripping flex all day, this is the sort of kit that saves your hands and stops costly damage. A proper Knipex wire stripper or flex cable stripping tool gives you cleaner prep, better repeatability, and less faff when you're moving from sheathing to cores to ferrules. You'll find Knipex Tools here for sparks, panel builders, and maintenance teams who need stripping and crimping kit that works first time.
What Are Knipex Wire Strippers Used For?
- Stripping flex for plug tops, appliances, and site power leads is quicker with a proper flex cable stripping tool that removes the outer sheath cleanly without chewing into the insulation underneath.
- Prepping singles and fine stranded conductors for terminals, connectors, and control gear is where a Knipex automatic wire stripper earns its keep, especially when you are repeating the same job across a full board or panel.
- Working on data, coax, and round cable installs is easier with tools like the Knipex ErgoStrip, which is built for awkward stripping jobs where a knife is slower and rougher.
- Crimping ferrules and terminals onto stripped conductors helps keep terminations neat and secure, particularly on switchgear, consumer units, and machinery where loose strands are asking for trouble.
- Sorting first fix and maintenance call-out wiring is faster when your stripper and crimper are matched to the cable sizes you actually use, cutting down rework and damaged cores.
Choosing the Right Knipex Wire Stripper
Match the tool to the cable you strip most. That is the bit that matters, not just buying the fanciest one on the page.
1. Flex and Round Cable vs Singles
If you spend your day on flex, round cable, and awkward outer sheaths, go for a Knipex flex stripper or cable stripper made for circular cable. If you mostly prep singles for terminals and accessories, a Knipex automatic wire stripper is the quicker shout.
2. Repetitive Board Work vs Odd Repair Jobs
If you are stripping dozens of conductors on panel work or second fix, self adjusting tools save real time and give cleaner repeat results. If it is more occasional snagging and repairs, a compact manual stripper can be all you need.
3. Stripping Only vs Strip and Crimp
If you are only exposing conductors, keep it simple with a dedicated stripper. If you are regularly fitting bootlace ferrules or terminals, a stripper crimper set or separate Knipex ferrule crimping tool makes more sense and keeps the finish tidy.
4. Match the Cable Size Range
Do not assume one tool covers everything. Check the cable sizes you actually work on, because a tool that is spot on for fine control wiring will not always be right for thicker flex or larger outer sheaths.
Who Uses These on Site?
- Sparkies use Knipex wire stripper tools for day to day cable prep, whether they are stripping twin and earth tails, flexes, singles, or control wiring before termination.
- Panel builders and industrial electricians swear by this sort of kit because repeat stripping and ferrule crimping needs to be clean and consistent, not guessed by eye with side cutters.
- Maintenance engineers keep a Knipex cable stripper and Knipex crimping tool close by for breakdown work, where fast repairs matter and there is no time to remake damaged conductors.
- AV, data, and controls installers reach for tools like the Knipex Lighting & Electrical range when they need to strip round cable and delicate insulation without making a mess of the inner cores.
The Basics: Understanding Wire Strippers and Crimpers
These tools all deal with cable prep, but they do different jobs. Get this bit right and you will buy once instead of ending up with the wrong tool in the bag.
1. Wire Strippers
A wire stripper removes insulation from the conductor without cutting into the copper. On site, that means cleaner terminations, fewer broken strands, and less chance of faults caused by rushed prep.
2. Cable Strippers
A cable stripper is usually for taking off the outer sheath from round cable or flex. That is what you want when prepping leads, data cable, or multi core cable before you even get to the inner conductors.
3. Crimpers
A crimping tool compresses a terminal or ferrule onto the stripped conductor so it stays secure in service. If you are using ferrules or terminals, stripping alone is only half the job.
Accessories That Keep Your Cable Prep Moving
A few small extras save a lot of messing about when you are terminating cable all day.
1. Ferrules
If you are stripping fine stranded conductors, do not stop there. A box of Knipex Ferrules saves you fighting stray strands at the terminal and gives a much neater finish in boards and control gear.
2. Cable Management Supplies
Once cables are stripped and terminated, you still need to keep the run tidy and protected. Knipex Cable Management bits help stop a clean wiring job turning into a tangled mess in trunking, panels, and enclosures.
3. Matching Crimping Tools
A proper crimper is what stops a good strip job being ruined by a poor termination. If you are regularly fitting ferrules or terminals, pair your stripper with the right Knipex crimping tool instead of trying to make do with one tool for everything.
Choose the Right Knipex Wire Stripper for the Job
Pick the tool by cable type first, then by how often you are doing the job.
| Your Job | Knipex Category or Type | Key Features |
|---|---|---|
| Stripping singles for sockets, switches, and board work | Automatic wire stripper | Self adjusting action, repeatable strip lengths, quicker on repetitive terminations |
| Removing outer sheath from flex and round cable | Flex cable stripping tool | Clean sheath removal, better control on circular cable, less risk of nicking inner cores |
| Data, coax, and awkward multi use cable prep | Knipex ErgoStrip | Compact shape, suited to several cable types, handy where a knife is too rough |
| Stripping then fitting ferrules on control wiring | Stripper and ferrule crimping setup | Clean conductor prep, secure ferrule fit, neater panel and enclosure terminations |
| Mixed snagging, maintenance, and call-out work | Compact stripper crimper set | Covers more than one task, saves space in the bag, useful for reactive jobs |
Common Buying and Usage Mistakes
- Buying a wire stripper for outer sheath work is a common one. It will slow you down and can mark inner insulation, so use a proper cable stripper or flex tool for round cable first.
- Assuming one crimper does every terminal type catches plenty of people out. Different terminals often need different die profiles, so always match the crimper to the connector you are fitting.
- Using the wrong size setting or wrong tool on small conductors can nick copper strands. That weakens the termination and is asking for heat or failure later, especially on fine stranded cable.
- Trying to strip flex with a knife to save time usually does the opposite. You end up with scored insulation, ragged sheath cuts, and more rework than if you had used the right stripper in the first place.
- Skipping ferrules on stranded conductors where they are needed makes terminations untidy and less secure. Use the right ferrule and crimper if you want a clean fit into terminals and devices.
Automatic Wire Strippers vs Cable Strippers vs Crimpers
Automatic Wire Strippers
Best for stripping individual conductors quickly and consistently, especially on repetitive electrical work. They are not the right pick for removing tough outer sheaths from flex or round cable.
Cable Strippers
Built for cutting and removing the outer jacket from flex, data, and round cable without digging into the cores. They are the cleaner option than a knife, but they do not replace a proper conductor stripper.
Crimpers
Used after stripping to secure terminals or ferrules onto the conductor. If your work ends at bare copper, you may not need one every time, but for panels and neat control wiring they are hard to do without.
Stripper Crimper Sets
A good option for mixed site work where bag space matters and you need to cover more than one task. They are handy for call-outs, though dedicated tools are often quicker if you repeat the same job all day.
Maintenance and Care
Keep the Blades Clean
Wipe off insulation dust, adhesive residue, and site grime after use. Dirty cutting edges drag through cable and make clean stripping harder than it needs to be.
Do Not Force the Wrong Cable
If the cable is outside the tool's size range, stop. Forcing oversized sheath or undersized conductors through the wrong stripper wears the tool and wrecks the finish.
Check Moving Parts
Automatic strippers and crimpers rely on smooth linkages and spring tension. If they start sticking, clean them out and inspect for wear before the job quality drops off.
Store Them Dry in the Tool Bag
Leaving hand tools wet in the van is a good way to invite rust and stiff pivots. A dry pouch or case keeps the mechanism cleaner and the cutting edges in better nick.
Replace Worn Tools Before They Damage Cable
Once a stripper starts nicking conductors or a crimper no longer gives a firm, even crimp, it is costing you time and trust in the finished work. That is the point to replace it, not carry on regardless.

Knipex Wire Stripper FAQs
What's the difference between a wire stripper and a crimper?
A wire stripper removes insulation from the conductor. A crimper fixes a terminal or ferrule onto that stripped conductor. One preps the cable, the other finishes the termination. If you are fitting ferrules or terminals, you often need both.
What's the Knipex ErgoStrip used for?
The Knipex ErgoStrip is used for stripping outer sheaths and insulation on several cable types, including round cable and data style work. It is especially handy when you want more control than a knife gives and a cleaner result on awkward cable prep.
Do Knipex crimping tools need different dies for different terminals?
Yes, many do. Different terminals and connector styles need the correct crimp profile, so always check what the tool is designed for. Using the wrong die can give a poor crimp that looks passable at first but will not hold up in service.
What cable sizes can Knipex strippers handle?
That depends on the exact tool. Some Knipex strippers are aimed at fine control wiring and singles, while others are built for larger flex or outer sheath work. Check the stated size range before you buy, especially if you jump between panel wiring and general site electrics.
Are Knipex strippers self-adjusting?
Some are, some are not. Knipex automatic wire stripper models are self adjusting and speed things up on repetitive work. Manual and specialist cable strippers rely more on the tool design and your setup for the cable being stripped.
Will these handle daily site use or are they more for bench work?
They are built for proper trade use, not just sitting in a workshop drawer. That said, use the right stripper for the right cable. Even good kit will struggle if you ask a light conductor stripper to do sheath work it was never meant for.
