NT-Cutter L-500GRP 18 mm Metal Auto-Lock Heavy-Duty Utility Knife

The NT-Cutter L-500GRP 18 mm Metal Auto-Lock Heavy-Duty Utility Knife is built for demanding cutting work in workshops, construction, maintenance, and packaging environments. It uses a snap-off blade with a segmented design, so worn sections can be snapped off to expose a fresh cutting edge without replacing the whole blade. The blade is also interchangeable: once the original is used up, it can be swapped for a compatible NT Cutter blade. This makes the tool suitable for repeated cutting tasks that go beyond what a standard craft knife can handle.

The body and handle are made from die-cast aluminium with a metallic grey finish. This all-metal construction gives the knife the rigidity needed for repeated use while keeping it light enough for single-handed operation over extended periods. A built-in slider controls blade extension and retraction, letting you set the cutting depth to suit different materials and tasks. The compact form suits a range of hand sizes and working positions. Overall, the construction is well suited to demanding environments where tool durability and blade control matter throughout the working day.
