k502x, Nylon Handle, Plain Edge, Nylon Sheath Take everything you expect from a traditional lockback folder. Then pile on the features—can opener, bottle opener, bit driver (with six screw bit tips), even a carabiner clip—but do it so the extra versatility isn't noticed until it's needed. What you get is a product engineers like to call "feature dense," which means the k502x and k503x provide maximum usefulness with minimum bulk.
