Deli Utility Knife, 18 Mm, Snap-Off Blade, Retractable, Sk5 Steel Blade For Durability, Perfect For Heavy-Duty Cutting Tasks - Yellow

The 18 mm blade provides a wider edge that handles thicker and stiffer materials. It’s well-suited for cardboard, foam board, thick packaging, and similar materials, as well as film in certain applications.

The blade is built with perforated segments. When the tip dulls, you can snap off a fresh segment along the perforation line to restore a sharp edge. Always extend or retract the blade safely and use steady, controlled pressure when refreshing segments.

The blade slides back into the housing when not in use, reducing the risk of accidental nicks and injuries. Use the slide to extend the blade only when you’re ready to cut, and retract it when you’re finished.

SK5 is a high-carbon steel known for good hardness and edge retention. Blades made with SK5 stay sharp longer and resist wear, offering durable performance for repeated cutting tasks.

Textured Grip Housing provides a secure, controlled hold for straight, confident cuts. The Guided Blade Channel helps keep the blade stable and reduces wobble for more accurate cuts. The Compact Body makes the knife easy to carry, store in pouches, and keep neatly in a desk or kit.

To refresh a dull tip, retract the blade and carefully snap off a fresh blade segment along the perforation line using steady pressure. Replace the blade only when the knife is safely retracted and, if needed, use pliers or a blade-spare container to handle broken segments. Dispose of used segments properly.

This 18 mm snap-off retractable knife is well-suited for classrooms, studios, and mailrooms. Use it for opening thick packaging, scoring and cutting cardboard, trimming foam board, and other light-to-medium-duty cutting tasks that require a controllable, safe tool.

Always retract the blade when not cutting, cut away from your body, secure the work material on a stable surface, and maintain a firm grip. Keep fingers away from the blade path, wear safety glasses if needed, and store the knife in a protective sheath or pouch when not in use.

Wipe the housing to remove dust or debris after use. Keep the blade segments dry and free of moisture to prevent corrosion. Store the knife in a dry place and ensure the blade is retracted when not in use.
