Knipex Knives & Blades
Knipex knife options are built for clean, controlled cuts on cable, insulation and site packaging, without the sloppy feel of cheap blades.
When you're stripping sheathing, trimming insulation or opening fixings all day, a proper Knipex knife earns its place fast. This is the sort of kit sparks and fitters keep close because the grip is right, the blade shape suits the job, and replacements are easy to sort. If you already trust Knipex Tools, this is the cutting end of the range worth keeping in the pouch.
What Are Knipex Knives Used For?
- Stripping outer jackets from cable runs is where a Knipex cable knife comes into its own, giving sparks better control when working back boxes, boards and containment without nicking what sits underneath.
- Opening site deliveries, insulation packs and boxed fixings is quicker with a Knipex utility knife that locks properly and does not feel loose in the hand halfway through a shift.
- Trimming conduit accessories, tapes, sleeving and light sheath materials during first fix is easier with the right blade profile, especially when you are working in tight risers or crowded cupboards.
- Cutting and shaping insulation or sheath materials on maintenance and retrofit jobs is cleaner with a sharp Knipex stripping knife that gives you a controlled pull rather than a ragged tear.
- Working from the pouch or van on snagging and final fit jobs is simpler when you have the right blade on hand, which is why many lads pair these with Knipex Cutting Tools rather than relying on one cheap knife for everything.
Choosing the Right Knipex Knife
Sort the right Knipex knife by the material you are cutting first. A blade that is right for cable work is not always the one you want for general site trimming.
1. Cable Knife or Utility Knife
If most of your day is spent stripping sheaths and working around live-installation rules, go for a Knipex cable knife or electricians knife with a blade shape meant for controlled cable work. If you are mainly opening packs, trimming sheet material and doing general van and site jobs, a Knipex utility knife makes more sense.
2. Fixed Blade or Folding Knife
If you want something ready the second it comes out the pouch, a fixed blade is the straightforward choice. If pocket carry and safer storage matter more when you are moving round site, a Knipex folding knife is easier to live with day to day.
3. Straight Blade or Hooked Blade
If you need cleaner scoring and trimming, stick with a straight edge. If you are drawing through outer cable jackets and want less chance of digging too deep, a Knipex hooked blade knife is usually the better shout.
4. Replaceable Blades Matter
If the knife is going to earn its keep every day, do not overlook blade changes. Replaceable Knipex knife blades save you forcing dull edges through work, which is when slips happen and cuts turn messy.
Who Uses These Knives on Site?
- Sparkies use a Knipex electricians knife and Knipex cable knife for stripping outer sheaths, trimming insulation and keeping cable prep neat before termination.
- Data installers and control panel fitters reach for these when they need tidy, accurate cuts in tighter spaces where a clumsy blade can ruin a cable run.
- Maintenance teams keep a Knipex utility knife in the van for everyday cutting jobs, from opening plant room deliveries to trimming labels, sleeving and light plastics.
- Fitters and site supervisors often carry a folding knife for quick snagging work because it is safer in the pocket and ready when packaging, tapes or light materials need cutting there and then.
Useful Extras for Knipex Knives
A decent knife is only half the job. The right spares and storage stop downtime and keep cuts clean.
1. Spare Knife Blades
Keep spare Knipex knife blades in the van or pouch so you are not forcing a dull edge through cable sheath or insulation. That is how you end up tearing material, slipping off line and wasting time cleaning up rough work.
2. VDE Knife Options
If you are working in environments where insulated cutting kit matters, look at Knipex VDE Knives & Blades. It saves carrying the wrong knife onto electrical work where proper insulated tools are the safer call.
3. Storage for Blades and Knives
Loose blades rolling round the van are asking for trouble. A proper setup from Knipex Tool Storage keeps spare blades, folding knives and cutting kit together where you can actually find them.
Choose the Right Knipex Knife for the Job
Match the blade style to the work, not just what is cheapest.
| Your Job | Knipex Knife Type | Key Features |
|---|---|---|
| Stripping outer cable sheaths on first fix | Cable Knife | Controlled blade shape, better grip, safer cutting along insulation and sheath materials |
| General site trimming and opening packs | Utility Knife | Fast blade access, easy replacements, handy for packaging, tapes and light materials |
| Working from a pocket on snagging jobs | Folding Knife | Compact carry, safer closed storage, quick to pull out for light cutting jobs |
| Drawing through outer jackets without digging in | Hooked Blade Knife | Hook profile helps protect what is underneath and keeps the cut tracking properly |
| Electrical work needing insulated cutting kit | VDE Knife | Insulated design suited to electrical environments where standard knives are not the right choice |
Common Buying and Usage Mistakes
- Buying a general utility knife for cable work and expecting fine control. It will cut, but it is easier to nick insulation or cores, so use a proper Knipex cable knife where cable prep matters.
- Carrying on with a blunt blade to save swapping it. That just means ragged cuts, more force through the hand and a higher chance of slipping, so keep fresh blades ready.
- Using the wrong blade profile for the material. A straight blade is not always best on outer sheaths, and a hooked blade is not ideal for every trim job, so match the shape to the task.
- Leaving spare blades loose in a pocket or van tray. It is poor practice, hard on the blades and easy to get cut, so store them properly with the rest of your cutting kit.
- Assuming any knife is suitable for armoured cable. Standard cable knives are for sheath work, not every stage of SWA prep, so check exactly what the knife is designed to do before you start.
Cable Knife vs Utility Knife vs Folding Knife
Knipex Cable Knife
Best when you are stripping cable jackets and need control more than speed. It is the right pick for sparks doing regular cable prep, but it is not the first thing you would choose for opening every delivery on site.
Knipex Utility Knife
This is the all-rounder for packaging, insulation, tapes and general trimming. It suits mixed trade work well, but for delicate sheath stripping it does not always give the same confidence as a dedicated cable knife.
Knipex Folding Knife
A folding knife is easier to carry in a pocket and safer when shut, which makes it handy for snagging, service calls and van work. The trade-off is that some lads still prefer a fixed blade when they are constantly cutting through the day.
Maintenance and Care
Keep Blades Clean
Wipe adhesive, dust and sheath residue off after use. A dirty blade drags through material and makes neat stripping harder than it needs to be.
Change Blades Early
Do not run a blade until it is completely spent. Once it starts tearing instead of cutting cleanly, replace it before it costs you control.
Check Locks and Hinges
On folding knives, make sure the lock engages properly and the hinge stays free of grit. If it starts feeling sloppy, sort it before carrying it daily.
Store Them Properly
Keep knives dry and out of loose van clutter. Proper storage stops damaged edges, accidental cuts and rust starting where dirt and moisture sit.
Replace Worn Kit When It Stops Feeling Safe
If the handle is cracked, the lock is unreliable or the blade retention is poor, retire it. A knife is not something to nurse along once trust has gone.

Knipex Knife FAQs
What knife is used by navy seals?
That is not really the right question for this page. Navy issue and military field knives are a different job entirely. A Knipex knife is built for trade work like stripping cable, trimming insulation and controlled site cutting, not combat or survival use.
What's a cable knife used for?
A cable knife is used for stripping the outer sheath from cables cleanly and with better control than a standard utility blade. It is especially useful for sparks working on first fix, board changes and maintenance where you need to expose cable without damaging the insulation below.
Are Knipex knife blades replaceable?
Many are, yes, but it depends on the exact knife. Replaceable blade models are the practical choice for regular use because you can keep the handle and just swap the edge when it starts dragging. Always check the individual knife listing before ordering spare blades.
What blade types do Knipex knives take?
That depends on the model. Some Knipex knives use dedicated blades matched to cable work or hooked cutting, while utility styles may use standard replaceable formats. The main thing is to buy blades that are made for that specific knife so fit and retention stay right.
Is a Knipex cable knife suitable for stripping armoured cable?
It is suitable for stripping outer sheath where the model is designed for cable work, but do not assume it covers every stage of SWA preparation. Armoured cable often needs a more specific process and sometimes different tools for the armour itself. Use the knife for the sheath work it is intended for and not as a one-tool answer for the whole job.
