The REDI features the all new REDI-Lock replaceable blade system, which lets you easily swap between 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 point blades (one with partial serration), 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, as the REDI is also the first Havalon to have spring assist for smooth, one hand opening.
