Never sharpen your knife again with Outdoor Edge's patented RazorSafe system. Simply push the lock button on the handle to remove and insert a razor sharp new blade. The 3.5" Onyx EDC is the perfect knife for everyday carry and DIY tasks. The black blade holder provides the thin razor blade with the strength of a standard blade. The handle is constructed from Grivory and offers a Trimond texture pattern with a metal pocket clip for carry. The double sided thumb studs allow for one-hand opening and each knife comes with three 3.5" drop point blades constructed from 420J2 stainless steel.
