Wiss Auto Retractable Utility Knife
Introducing the Wiss Auto-Retracting Utility Knife.
Unlike standard "self-retracting" utility knives,
the Wiss Auto-Retracting Knife retracts the blade
automatically the moment it loses contact with the
material being cut. The blade automatically retracts
even if the user is still holding the blade slider
forward in the 'open' position.
