Heavy-Duty Cutter Knife 18mm - Auto-Lock Snap-Off Blade

Cut Through Anything. Lock It. Trust It.

The Heavy-Duty Cutter Knife is built for those who need more than a basic paper cutter. With an 18mm wide snap-off steel blade and a powerful Auto-Lock mechanism, this cutter delivers professional-grade cutting performance for thick paper, cardboard, foam, tape, packaging, and more.

The bold yellow and black ergonomic body fits comfortably in your hand, giving you full control with every cut. The Auto-Lock feature keeps the blade firmly in place during use — no slipping, no wobbling, just clean, confident cuts every time. When you're done, retract the blade safely with a single slide.
