Crescent CTK18SO 18mm Snap-off Utility Knife

Product Description

The CRESCENT CTK18SO is an 18mm snap-off utility knife built around an everyday-carry design profile. It delivers consistent cutting performance across the full lifespan of each blade segment by allowing technicians and tradespeople to snap off dull points and expose a fresh edge without stopping work. The knife ships with 2 replacement blades, each featuring 8 scored snap-off segments. The removable end cap doubles as a blade-snapping tool and stores up to 3 spare blades, keeping replacements on hand without a trip back to the truck. Weighing 0.32 pounds, it is compact and light enough for all-day carry on any jobsite.

This knife suits general trade use across HVAC, electrical, plumbing, and construction applications. It is appropriate for cutting insulation, tape, wire sheathing, gasket material, and similar jobsite materials. The tool-free blade change and integrated spare-blade storage make it practical for technicians who need a reliable cutting tool readily accessible during service calls or installation work.

Installation Notes

No installation is required. When snapping off a dull blade segment, use the integrated end cap tool rather than pliers or bare hands to reduce the risk of blade fragment injury. Dispose of snapped segments in a puncture-resistant sharps or blade container per jobsite safety requirements. Store the knife with the blade retracted when not in use.
