This Heavy-Duty 18 mm Screw-Lock Utility Knife is engineered for heavy cutting applications in construction, warehouse packaging, flooring, and general trade work.

The knife is constructed with a durable high-impact plastic housing in high-visibility yellow/blue and reinforced with a heavy-gauge stainless steel inner channel for smooth blade extension and structural strength. Uses standard 18 mm segmented snap-off replacement blades, allowing instant access to a fresh razor-sharp cutting edge. Individually poly-bagged for individual retail sale.

Key Features & Standards

-
Stainless Steel Guide Track: Reinforced metal blade track ensures smooth sliding action and rigid support under heavy load.
-
Ergonomic High-Visibility Body: Contoured grip design reduces hand strain, while the bright yellow body makes it easy to locate on crowded jobsites.
