Overview

The Westcott 17531 Finger Loop Replaceable Safety Cutter is engineered for environments where safe, efficient cutting is a daily necessity. Built around an auto-retractable ceramic blade, this cutter addresses the primary concern of workplace cutting injuries by ensuring the blade retracts whenever it loses contact with the material being cut. A dedicated lock-out button adds a second safety layer, keeping the blade fully housed during storage or transport. The ABS plastic frame provides high-impact durability while keeping the overall weight down to just 1.13 ounces.

What sets this cutter apart from basic box cutters is its ergonomic finger loop design, which gives the user a secure, controlled grip during repetitive cutting tasks. The ambidextrous finger slide allows operation from both the top and side positions, accommodating left- and right-handed users equally. The ceramic blade offers a meaningful advantage over steel—it maintains its cutting edge substantially longer under normal use, reducing the frequency of blade changes. When replacement is needed, the disposable blade swaps out easily with Westcott's compatible ceramic blades (part 00648). At 7.63 x 3.13 x 0.75 inches, it is compact enough for a pocket or lanyard while remaining comfortable to handle throughout a shift.
