OLFA L-1/SOL 18mm Ratchet-Lock Utility Knife with Solid Blade

The OLFA L-1/SOL is a classic 18mm utility knife designed for everyday jobsite cutting with a thicker, non-segmented solid blade. The 0.5 mm blade stock resists flex when slicing rigid foam, plastics, flooring, and dense packaging. A knurled ratchet-lock wheel lets users set the blade depth exactly where they want it and keep it there, improving control on long scoring cuts or deep passes. With up to 85 mm (3.3″) cutting depth, this 18mm knife covers a surprising range of building materials while staying compact enough for pouch carry. Crews who prefer a single-piece blade (no snap-off sections) will appreciate the predictable edge life and stable feel when pushing through thicker materials. The yellow, high-visibility handle is easy to spot in a busy shop or on a remodel site, and the simple, field-proof mechanism stands up to daily use without fuss.
