$18.29

The Portwest KN40 Retractable Safety Cutter is a heavy‑duty cutting tool engineered for safe, reliable performance in fast‑paced work environments. Built from a durable zinc‑alloy body with rubberized grip accents, it provides stability and control during repetitive cutting tasks. The auto‑retracting blade disengages the moment it leaves the cutting surface, reducing the risk of accidental injury. A quick blade‑change system keeps downtime minimal, and the integrated lanyard point supports secure, on‑person carry.


Key Features:



  • Auto‑retracting blade disengages immediately after leaving the cutting surface for enhanced safety.

  • Quick blade‑change system minimizes downtime during high‑volume use.

  • Durable zinc‑alloy body with rubber grip for comfort and control.

  • Designed for heavy, everyday industrial use.

  • Lanyard‑compatible for secure attachment and reduced drop risk.
