OLFA L5-AL Heavy Duty Cutter (18mm)

The OLFA L5-AL Heavy Duty Cutter (18mm) is engineered for professionals who need high cutting force, maximum durability, and secure blade control during demanding material cutting. Built with an industrial-grade handle and auto-lock mechanism, this heavy-duty utility cutter delivers reliable performance in construction, packaging, warehouse, fabrication, and workshop environments.

The fiberglass-reinforced handle and elastomer rubberized anti-slip grip ensure controlled cutting pressure, even when working with dense materials. The ergonomic body is shaped for firm handling and long-term use, while the rugged design withstands repetitive heavy cutting without flexing. It also features a built-in hard metal pick for multi-purpose applications.

A full stainless-steel blade channel secures the blade along its entire length, maintaining alignment for clean and stable cuts through thick or rigid materials. The auto-lock slider enables quick, one-hand blade positioning through preset stops, ensuring safe and consistent blade extension.

Factory-loaded with an OLFA LBB Ultra-Sharp Heavy-Duty Black Blade, the L5-AL provides extra sharpness and edge retention for demanding applications. Each 18mm blade includes multiple snap-off segments for convenient, on-the-spot edge renewal. When a segment dulls, simply snap to reveal a fresh cutting edge. Blade replacement is tool-free, designed for professional workflow efficiency.

Why Fiberglass Body Matters

Unlike common plastic utility knives, the OLFA L5-AL uses a fiberglass composite that:

• resists flexing
• prevents cracks over long use
• improves grip under pressure
• withstands solvents & adhesives used in leatherwork
• maintains stability while trimming hard materials

This makes it exceptionally reliable for professional cutting tasks where accuracy is important.
