Knipex Side Cutters & Diagonal Cutters
Knipex side cutters are the go-to for clean, controlled cuts on cable, ties and wire when cheap cutters start chewing instead of cutting straight.
On site, these are the pair you reach for all day without thinking about it. Knipex side cutters, also called Knipex diagonal cutters, are built for sparks, panel fitters and maintenance teams who need sharp jaws, proper leverage and edges that stay keen under regular use. If you already trust Knipex Tools, this is the range to start with. Pick the right size and jaw type, and get cutters that earn space in the pouch.
What Are Knipex Side Cutters Used For?
- Cutting twin and earth, singles and control cable during first fix, where you need a clean snip that does not flatten the insulation or leave a ragged end.
- Trimming cable ties, soft wire and small fixings in panels, trunking and containment, especially when you are working one-handed up steps or in tight cupboards.
- Snipping binding wire, light fencing wire and general site wire on refurbs and fit-outs, where blunt cutters quickly start slipping and bruising your hand.
- Working through repetitive electrical and mechanical assembly jobs on the bench, where Knipex diagonal cutters save effort with better leverage and cleaner edge geometry.
- Reaching into awkward corners behind sockets, inside enclosures and around packed services, where a compact cutter is easier to control than bigger pliers or snips.
Choosing the Right Knipex Side Cutters
Sorting the right pair is simple: match the cutter to the wire you actually cut all week, not the odd job you do once a month.
1. Size Matters More Than Most Think
If you want an everyday pouch tool for electrical work, the smaller sizes are easier to carry and control in boxes and panels. If you are regularly cutting thicker cable, tougher wire or doing repeated bench work, step up in length for better leverage and less hand strain.
2. Standard Cutting Edges vs High Leverage
If you are mostly trimming ties, soft copper and light wire, a standard pair is plenty. If you are on repetitive cuts or harder materials, go high leverage. You will feel the difference by lunchtime, especially when the cheap pair would already be biting into your palm.
3. Insulated or Standard Handles
For general bench, workshop and dead work, standard handles are fine. If the job calls for insulated hand tools, do not chance it. Go straight to the proper VDE-rated version and keep your kit in line with the work.
4. Hard Wire Capability
Do not assume every cutter handles the same material. If hardened or piano-style wire is part of the job, check the spec before you buy. For heavier stock and tougher cuts, you may be better moving up to Knipex Bolt Cutters instead of wrecking a smaller pair.
Who Uses These on Site?
- Sparkies swear by Knipex side cutters for stripping back the clutter on cable runs, trimming ties in consumer units and making fast, neat cuts during first and second fix.
- Panel builders and control fitters use them on the bench all day for cable prep and tidy finishing, because a sharp pair makes repeated cuts less of a fight.
- Maintenance engineers keep a pair in the bag for quick repairs on plant, gates, housings and small wire jobs, where you need control more than brute force.
- Telecoms and data installers reach for compact Knipex diagonal cutters when dressing cabinets and trimming tails in tight spaces where bigger cutters are just clumsy.
- If you need insulated options for live-working rules, look at Knipex VDE Side Cutters & Diagonal Cutters rather than using standard handles where they should not be.
Useful Extras for Knipex Side Cutters
A couple of sensible add-ons save you carrying the wrong cutter or ruining a good pair on the wrong material.
1. Tool Pouches and Holsters
A proper pouch keeps your Knipex side cutters where your hand expects them, which matters when you are up steps, in a ceiling void or moving round a live job. It also stops the cutting edges getting knocked about loose in the van.
2. VDE Cutter Options
If your work crosses into insulated hand tool territory, keep a dedicated VDE pair rather than mixing jobs with standard cutters. It saves the usual last-minute panic when you realise the pair in your pouch is wrong for the task.
3. End Cutters and Nippers
Side cutters are not the answer to every cut. A pair from the Knipex Nippers range is better when you need to pull and snip close, especially on tying wire, staples or awkward flush cuts.
Choose the Right Knipex Side Cutters for the Job
Use this quick guide to avoid buying too small, too bulky or the wrong cut rating.
| Your Job | Knipex Side Cutters Type | Key Features |
|---|---|---|
| Daily electrical first and second fix | Compact standard side cutters | Easy pouch carry, good control in boxes and trunking, clean cuts on common cable and ties |
| Repeated bench work and panel wiring | High leverage diagonal cutters | Less effort per cut, better for repetitive use, easier on the hand over a full shift |
| Working where insulated tools are required | VDE side cutters | Insulated handles, suited to regulated electrical work, safer choice than standard grips |
| Cutting tougher wire more often | Larger cutters with hard wire rating | Stronger cutting edges, more leverage, better suited to thicker and harder materials |
| Close flush cuts and awkward tie wire jobs | Nippers or end cutters | Better access for close cutting, less twisting at the wrist, cleaner finish in tight spots |
Common Buying and Usage Mistakes
- Buying purely on size and ignoring cut rating is the usual mistake. A small pair might feel handy, but if you use it on wire it was never meant for, you will nick the edges and shorten its life fast.
- Using side cutters as a general pry tool or twisting tool soon knocks them out. They are for cutting, not levering clips open or yanking nails, so keep a different tool for abuse jobs.
- Assuming side cutters and diagonal cutters are different products catches people out. In most site use, they are the same style of cutter, so focus on size, leverage and insulation rather than getting stuck on the name.
- Choosing standard handles for work that needs insulated tools is a bad shortcut. If the task calls for VDE kit, buy the proper rated pair and keep them separate from your general hand tools.
- Trying to cut hardened wire with a light-duty pair is how good cutters get ruined. Check the spec first and move up to a tougher model when the material changes.
Standard Side Cutters vs High Leverage vs VDE Cutters
Standard Side Cutters
Best for everyday cable, tie and light wire cutting where you want a compact tool that lives in the pouch. They are quick, simple and easy to control, but they are not the one to force through tougher wire all week.
High Leverage Diagonal Cutters
This is the better choice for repetitive cutting and thicker material because the handle and jaw design do more of the work for you. Slightly bulkier, yes, but far less tiring when you are making cut after cut on a full shift.
VDE Cutters
Pick these when the job calls for insulated hand tools. They do the same core cutting job, but the key point is compliance and safety on electrical work, not just comfort in the hand.
Maintenance and Care
Wipe the Jaws After Dirty Work
Dust, adhesive and damp site muck soon build up around the cutting edges and pivot. A quick wipe at the end of the day keeps the action smooth and stops grit wearing the joint.
Keep Them Dry in the Van
Even good cutters do not like living wet at the bottom of a toolbox. Dry them off after outside work and store them somewhere they are not sat against damp rags or leaking bottles.
Use the Right Pair for the Right Material
Nothing kills cutting edges quicker than forcing them through wire beyond their rating. Keep your main pair for the jobs they suit and use heavier cutters when the material steps up.
Check the Pivot for Smooth Action
If the joint starts feeling stiff, sort it early. A tiny amount of suitable oil on the pivot and a clean-out beats fighting sticky handles on every cut.
Replace When the Edge is Gone
Once cutters start crushing instead of cutting cleanly, they are costing you time. If the edges are nicked or the jaws no longer meet properly, retire them from fine work and replace them.

Knipex Side Cutters FAQs
Are Knipex cutters good for professionals?
Yes. That is exactly who most of this range is aimed at. Knipex cutters are well regarded on site because the edges stay sharp, the leverage is right and the handles hold up to daily use better than bargain-bin pairs. They are not magic, but if you use the correct model for the wire you are cutting, they last and cut cleanly.
What are Knipex side cutters used for?
Mainly for cutting cable, copper conductors, cable ties, soft wire and other small site materials cleanly and with control. Sparkies use them constantly in boxes, boards and containment. Fitters and maintenance teams use them for trimming, snipping and tidy finishing in tighter spaces.
Can Knipex side cutters cut hardened wire?
Some can, some cannot, so do not guess. Knipex makes different side cutters with different cutting capacities. If hardened wire is part of your day-to-day work, check the product spec and choose a model rated for it. If the stock is too tough, step up to a heavier cutter instead of risking the edges.
What's the difference between side cutters and diagonal cutters?
In most practical buying terms, there is not much in it. Side cutters and diagonal cutters usually refer to the same general tool style, with angled cutting jaws designed for clean snips close to the work. What matters more is the size, leverage, handle type and wire capacity.
What size side cutters should I choose?
Go smaller if you want a light everyday pair for pouch carry, tight boxes and light cable work. Go larger if you regularly cut thicker wire or spend all day making repeated cuts, because the extra leverage saves your hand. Buy for your main weekly job, not the one odd task you did last month.
