Ready for Heavy-Duty Work
The OLFA L-5 18mm Heavy Duty Utility Knife is a professional utility knife designed for precision cutting in construction, flooring, drywall, and general jobsite use. Its fiberglass reinforced handle with an anti slip grip provides comfort and control, while the ratchet lock mechanism allows quick one touch blade adjustment. A durable stainless steel blade channel ensures strength and stability, and the preloaded LBB 18mm Ultra Sharp Black Snap Off Blade, 25 percent sharper than standard blades, delivers clean cuts with eight snap off segments for long lasting sharpness. The tool free blade change keeps work efficient, and the integrated multi purpose metal pick adds versatility for tasks like removing caulk, opening lids, and detail work without damaging the blade.
