Cutting brake and gear cables cleanly is one of those tasks that separates a professional finish from a ragged one. The right cable cutter leaves a clean, fray-free end that threads through cable stops easily and creates precise, consistent shifting and braking. Here are the best bike cable cutters available in the UK.

Buying Guide
Never use scissors or standard wire cutters for bike cables. The result is invariably a frayed, unusable end that causes problems during installation.
Housing cutters need to handle two different materials — spiral wound housing and compressionless housing — with different internal structures. Make sure your cutter handles both.
After cutting cable housing, use a bradawl or similar tool to ensure the inner liner is open before fitting a ferrule. Even the best cutters can compress the liner slightly.
A good cutter should last many years with minimal maintenance. Keep the blade clean and occasionally apply a drop of oil to the pivot to maintain smooth operation.
If you are only doing occasional cable changes, the mid-range options provide excellent value. Reserve the professional tools for high-frequency use where blade longevity matters.

Final Thoughts
A proper cable cutter is a modest investment that makes a significant difference to the quality of your cable work. The Park Tool CN-10 is the professional choice, but the Shimano and Jagwire options offer excellent performance at a lower price point for regular home use.
Buying Guide
Bicycle cable cutters are specialist pliers designed to shear brake and gear cables — typically 1.1mm to 1.5mm stainless steel strands — plus outer cable housing cleanly and squarely in a single cut. Unlike ordinary wire cutters, quality cable cutters produce a flat, burr-free end that threads through cable end-caps and cable stops easily, preventing the fraying that causes poor brake feel and imprecise gear shifting.
| Factor | What to Look For |
|---|---|
| Blade Material and Hardness | Hardened carbon steel or high-speed steel (HSS) blades maintain their edge through hundreds of cuts. Cheaper tools use softer steel that deforms after a dozen cuts, leaving ragged, frayed cable ends. Look for blades rated to cut stainless steel cable specifically — standard electrician’s cutters may not be hard enough and will crush rather than shear the strands. |
| Cutting Capacity | A good bicycle cable cutter should handle inner cable (1.1 to 1.5mm), compressionless housing (up to 5mm outer diameter), standard spiral housing (4 to 5mm), brake housing and hydraulic hose. Tools that cover all of these in a single head — such as the Park Tool CN-10 — avoid the need for separate tools for different cable types. |
| Blade Geometry | The shearing edge should be ground at a steep angle — approaching 90 degrees — to produce a flat, square cut rather than a pinched or angled one. Angled cuts on inner cable leave a spike that is difficult to thread through a cable stop; angled outer cable cuts leave uneven ends that do not seat correctly in ferrules, causing brake and gear cable performance to suffer. |
| Ergonomics and Handle Length | Spring-loaded return action reduces hand fatigue during repeat cuts on a multi-bike workshop session. Handles long enough to provide adequate mechanical advantage — around 180mm overall — prevent the effort needed to close the blades from pushing the cable sideways rather than cutting it. Soft rubber grips are a bonus for extended workshop use. |
| Valve Core and Ferrule Tools | Some cable cutters include additional features such as a ferrule crimper, valve core remover or inner cable end-cap crimper. The Park Tool CN-10 and Shimano TL-CT12 both include a ferrule-fitting step in their design. These extras are genuinely useful and save the cost of separate tools for a fully equipped home workshop. |
