Heavy-Duty 18 mm Snap-Off Blade Utility Knife

The Superior Steel UK758 Heavy-Duty 18 mm Snap-Off Blade Utility Knife is built for precise general-purpose cutting tasks in the shop, on the jobsite, or around the home. Its robust construction and triple-honed black SK5 snap-off blade deliver the strength and cutting performance needed for cardboard, carpet, foam, PVC, tape, leather, and other common materials. The 18 mm snap-off blade design allows worn sections to be removed for a fresh cutting edge, while the one-button smooth blade advance locks in place at multiple cutting depths for added control. A tool-free blade change system and locking switch support safer operation and faster blade replacement during repeated use. Finished with a rubberized handle, thumb rest, and integrated lanyard hole, this knife provides a secure grip and convenient handling for demanding cutting applications.
