STANLEY FatMax Retractable Safety Knife with Plier Grip, Die-Cast Metal Handle, Tool-Free Blade Change, 1 Blade Included (FMHT10370-0)

Built around a die-cast zinc alloy handle that shrugs off drops and daily abuse, the STANLEY FatMax Retractable Safety Knife FMHT10370-0 pairs an interlock mechanism with a tool-free quick-change system for uninterrupted heavy-duty cutting. The ergonomic plier grip keeps your hand locked in a natural position, while the retractable blade and integrated storage for up to five blades put safety and convenience within thumb's reach.

Overview

This STANLEY FatMax safety knife is engineered for professionals who demand both toughness and precision. The die-cast metal body provides a solid, balanced feel, and the plier-style grip reduces hand fatigue during repetitive cutting tasks. A manual retraction mechanism with a secure locking system lets you extend the blade to multiple positions, then retract it fully for safe pocket or tool-belt carry. When the handle is opened for blade access, the interlock prevents the blade from being exposed, eliminating accidental cuts during blade changes.
