Knipex Snips & Shears
Knipex snips are for clean, controlled cutting of sheet metal, cable, insulation and site materials where cheap blades twist, snag or blunt too soon.
When you're trimming trunking, cutting thin sheet, or snipping cable ties and insulation on the hop, decent snips save time and your hands. Knipex snips, Knipex shears and Knipex tin snips are the sort of cutting tools trades keep close because the edges stay true and the grips make sense for all-day use. If you're working across metalwork, electrical fit-out or general install jobs, start with the cut you need and pick the right pattern from the range.
What Are Knipex Snips Used For?
- Cutting sheet metal for ducting, trunking covers, flashing and light fabrication work is where Knipex tin snips earn their keep, giving you a cleaner line without folding the material over.
- Trimming cable insulation, rubber, plastic sheet and tougher packaging on first fix or maintenance jobs is easier with Knipex universal shears that open wide and keep cutting properly right to the tip.
- Working through multi-core cable and finer copper conductors on electrical installs suits Knipex cable shears and Knipex electricians shears, especially when you want a neat cut without crushing the cable end.
- Snagging jobs in plant rooms, risers and service cupboards often call for compact Knipex snips 160mm, where you need one-handed control and enough bite to cut awkward material in a tight spot.
- Shaping curves and straight runs in thinner metal sheets for roofing, cladding or general site repairs is exactly the sort of work Knipex aviation snips are built to handle.
Choosing the Right Knipex Snips
Sorting the right pair is simple: match the blade pattern to the material and the cut, not just whatever looks sharpest in the van.
1. Metal Cutting vs General Site Cutting
If you are mainly cutting sheet metal, go straight to Knipex tin snips or Knipex aviation snips because they are shaped to keep the cut moving without chewing the edge. If the job is more insulation, rubber, cable ties and mixed site materials, Knipex universal shears make more sense.
2. Straight Cuts vs Curves and Tight Sections
If you are making long straight cuts in flashing or light sheet, pick a straight-cut pattern. If you are working curves, corners or awkward access around installed sections, a more compact snip or aviation style is easier to control and less likely to kink the material.
3. Cable Shears vs Electricians Shears
Do not treat them as the same thing. If you need clean cable cuts without crushing conductors, buy proper cable shears. If you are doing lighter electrical trimming, stripping tasks and general install work, electricians shears are the handier everyday option.
4. Site Access and Safety
If you are working in switchrooms or around live-rated procedures, look at Knipex VDE Snips & Shears. If you are up towers, on access kit or over finished areas, a tether-ready version is worth it from day one.
Who Uses These on Site?
- Sparkies use Knipex electricians shears and cable shears for trimming insulation, cutting smaller cable cleanly and dealing with the constant run of ties, sleeving and packaging that comes with fit-out work.
- HVAC fitters and ductworkers swear by Knipex snips when cutting and shaping sheet metal because a clean edge saves fighting warped sections during assembly.
- Roofers, cladders and general builders reach for Knipex tin snips when flashing, thin sheet and metal trims need adjusting on the spot instead of heading back to the bench.
- Maintenance teams keep a pair in the bag for all-round site cutting, especially where plastic, rubber, light metal and odd fixings all turn up in the same day.
- Anyone working at height should look at Knipex Tethered Snips & Shears so dropped tools do not become another site problem.
The Basics: Understanding Knipex Snips and Shears
These all cut, but they do not all cut the same thing the same way. Get the basic type right and the job goes quicker, cleaner and with a lot less hand strain.
1. Snips for Sheet Material
Snips are built to bite into thinner sheet and keep moving through the cut. That matters when you are trimming metal trunking lids, flashing or light gauge sheet, because the wrong tool will just bend the workpiece and leave a rough edge.
2. Shears for Controlled General Cutting
Shears are often the better choice for mixed materials like rubber, plastic, insulation and lighter electrical tasks where you want a smoother, cleaner action. They are the pair that usually stays in the pouch because they cover a lot of small cutting jobs without fuss.
3. Cable Shears for Round Section Cuts
Cable shears are shaped to cut cable cleanly rather than flatten it. On site that means tidier terminations, easier dressing-in and less damage to the conductor than you get from forcing cable through the wrong snip.
Useful Extras for Knipex Snips and Shears
A few add-ons and companion tools make these far more useful on site and stop you ruining the cutting edge on jobs they were never meant for.
1. Tool Tethers and Lanyard Setups
If you are working off steps, towers or scaffold, tethering stops a dropped pair turning into a near miss below. It is a simple fix that saves a lot of grief on sites with strict work at height rules.
2. Protective Holsters or Pouches
Do not leave good snips loose in the tool bag with screws, blades and other steel knocking about. A proper pouch protects the edge, keeps them to hand and stops you blunting them before the job even starts.
3. Dedicated Knives for Non-Shear Jobs
For foil, membrane, carton and finish trimming, use Knipex Knives & Blades instead of abusing your snips. It keeps the cutting edges for the work they are actually designed to do.

Common Buying and Usage Mistakes
- Buying general shears for sheet metal work is a common one, and it usually ends with twisted cuts and sore hands. If metal is the main job, buy proper Knipex tin snips or aviation snips.
- Using snips on cable when you really need cable shears can crush the conductor and leave untidy ends. Match the tool to the cable type if you want cleaner terminations and less rework.
- Forcing snips past their thickness limit blunts the edges fast and can spring the blades out of line. Check the material before you start and step up to the right pattern instead of trying to bully it through.
- Throwing snips loose in the bottom of a tool bag wrecks the cutting edge quicker than most people realise. Keep them protected in a pouch or separate section so they stay sharp.
- Using one good pair for every cutting task on site is false economy because adhesive, foil, screws and rough materials all shorten blade life. Keep separate cutters for separate jobs.
Tin Snips vs Aviation Snips vs Universal Shears
Tin Snips
Best for straightforward sheet metal cutting where you want a clean, predictable line. They are the sensible pick for flashing, light sheet and trunking parts, but they are not the best choice for mixed material jobs.
Aviation Snips
These give you more leverage and better control on curves, corners and tighter cuts in thin metal. If you shape material regularly rather than just trimming it, aviation snips are usually the better buy.
Universal Shears
Universal shears suit fitters and sparkies who cut a mix of insulation, plastic, rubber, foil and lighter site materials through the day. They are more versatile, but they are not a replacement for proper metal snips on fabrication work.
Cable Shears
If your main concern is cutting cable cleanly without flattening it, cable shears win easily. They are not for sheet metal, but for electrical prep they save a lot of mess and make the next stage easier.
Maintenance and Care
Wipe Down After Metal Cutting
Metal dust and fine swarf sit in the pivot and along the blades, which makes the action feel rough over time. Give them a quick wipe after use, especially after cutting coated sheet or anything dirty.
Keep the Pivot Moving
A drop of light oil on the pivot now and then keeps the action smooth and stops stiffness creeping in. If the snips start feeling gritty, sort it early before wear builds up.
Store Them Properly
Do not chuck them in with loose fixings, masonry bits and other cutters. A dry pouch or dedicated tool roll keeps the edges straighter and stops avoidable knocks.
Use the Right Tool for the Material
The best way to make snips last is not to misuse them. Cutting material that is too thick, too hard or full of hidden staples will shorten blade life faster than anything else.
Replace When the Cut Stops Being Clean
If they start folding metal, chewing insulation or needing too much force, do not keep battling on. Once performance drops off, replacement is usually quicker and safer than dragging a worn pair through live site work.

Knipex Snips FAQs
What are Knipex snips used for?
Knipex snips are used for controlled cutting of thin sheet metal, flashing, trunking parts, insulation, rubber, plastics and general site materials, depending on the pattern. The main thing is picking the right type. Tin snips are for sheet, universal shears are for mixed materials, and cable shears are for cleaner cable cuts.
Can Knipex shears cut sheet metal?
Yes, some can, but not every pair in the range is meant for it. If sheet metal is your regular job, buy Knipex tin snips or Knipex aviation snips rather than general shears. You will get a cleaner cut, less distortion and a lot less effort through the handles.
What is the difference between snips and shears?
On site, snips usually mean tools aimed at cutting thinner sheet materials, especially metal, while shears are often used more broadly for controlled cutting of cable insulation, rubber, plastic and mixed materials. There is some overlap, but the blade shape and intended material are what matter when choosing.
Are Knipex electricians shears able to strip cable?
Some Knipex electricians shears are designed with extra functions for common electrical tasks, including cable-related work, but not every model strips cable in the same way. Check the exact spec before buying. For regular cable prep, many sparks still keep dedicated strippers alongside their shears.
What thickness of metal will Knipex snips cut?
That depends on the exact snip type and the metal itself. Thin sheet, flashing and lighter gauge materials are the usual territory. Do not guess from looks alone. Check the stated cutting capacity for mild steel, stainless or non-ferrous material, because forcing past the rating will blunt the edges fast.
Are Knipex snips worth it for everyday site use?
Yes, if you are using them regularly. Knipex kit is generally bought by trades who are fed up with blades going slack, rough pivots and handles that punish your hands by lunchtime. They are not magic, but they do put up with daily site use better than throwaway pairs.
Do I need separate cutters as well as snips?
Usually, yes. Snips and shears are brilliant for the jobs they are made for, but they should not be doing everything. For harder wire and regular cutting work, keep a look at Knipex Cutters & Scissors so you are not wrecking your snips on the wrong material.
What else should I look at if this job needs more than snips?
If the job includes general trimming, heavier cutting and other prep work, it is worth checking the wider Knipex Cutting Tools range. That way you can keep the snips for clean finishing work and use the right cutting tool for everything else.
