Built Tough for the Trades

The OLFA 18mm L-1 Ratchet-Lock Utility Knife is a trusted tool for professionals in construction, manufacturing, and general trades. Built with a durable ABS plastic handle, this classic knife is designed to withstand tough jobsite conditions. Its contoured grip fits comfortably in hand for all-day use, and for added control, users can upgrade to the L-2 model with an anti-slip rubber inset.

The ratchet-style locking mechanism allows for precise blade positioning, while the stainless-steel blade channel supports the full length of the blade for strong, stable cutting.

Preloaded with a tough 18mm Silver Snap Blade, the L-1 is ready for action. Each blade includes eight deep-etched snap segments, allowing users to quickly refresh the edge without tools. When a segment dulls, simply snap it off and keep working—no downtime, no extra tools required.
