The Havalon Knives REDI EDC Folding Knife is the first to feature Havalon's REDI-Lock replaceable blade system, which lets you easily swap blade styles of semi-permanent AUS-8 steel blades. Unlike the original Piranta line, REDI blades are designed for extended use and abuse, and can even be re-sharpened. Each REDI comes with two drop points, one partially serrated and one plain edge, a blade holder for extra blade storage, and a T5 Torx bit so you can reposition the pocket clip. The innovation doesn't stop there though, as the REDI is also the first Havalon to have spring assist for smooth one hand opening.
