Crescent ctk9so 9mm Snap-off Blade Utility Knife

Product Description

The CRESCENT ctk9so is a 9mm snap-off blade utility knife built for tradespeople who need a reliable cutting tool on the jobsite. The knife features a thumb bridge that keeps the hand away from the blade channel during use, reducing fatigue and improving control on extended cuts. A tool-free blade change system lets technicians swap blades without reaching for a screwdriver. The removable end cap stores up to three spare blades inside the handle, keeping replacements within reach without requiring a separate parts pouch.

The ctk9so is suited for general trade use across HVAC, electrical, plumbing, and construction applications. It handles insulation scoring, sheathing cuts, vapor barrier trimming, and duct tape work. The ergonomic grip design reduces hand strain during repetitive cuts, making it practical for full-day use on residential and light commercial jobs.

Installation Notes

Use the removable end cap as the blade-snapping tool rather than fingers or pliers to reduce laceration risk when removing dull blade segments. Always retract or cap the blade before setting the knife down or placing it in a tool bag. Snap-off blade utility knives do not require licensed trade installation and are general-purpose hand tools subject to standard jobsite safety practices.
