Cable housing cutters either work or they don't—there's no middle ground. Dull or poorly designed cutters crush housing instead of slicing it clean, leaving you with a mangled end that needs filing, flares poorly, and creates friction points that affect shifting and braking performance. The Park Tool CN-10 Professional Cable and Housing Cutter addresses this with a compound leverage design that multiplies your hand pressure, delivering clean cuts through both cable and housing without the squeeze fatigue that cheaper tools cause.

The cutting head geometry handles the different materials you'll encounter in a cable job. Brake housing with its coiled steel liner, shift housing with its parallel strands, compressionless housing, and the cables themselves all cut cleanly when the blade geometry matches the task. The CN-10's hardened steel jaws maintain their edge through years of shop use, and the bypass cutting action shears rather than crushes. That matters most with compressionless shift housing, where a crushing cut closes the inner diameter and creates drag on the cable.

An integrated crimping station behind the pivot handles cable end caps without reaching for a second tool. The awl tip stored in one handle opens up housing ends that need a slight flare for ferrule seating—pull it out, ream the housing bore, and seat your ferrule without hunting for a pick or nail. These details separate a purpose-built cable tool from general-purpose wire cutters that technically cut cable but leave you cleaning up after every snip.... Read More
