Each blade comes sharpened and ready for attachment and use on your WildCard knife's handle. These are super handy if you forget to remove your WildCard knife from your wallet before going through airport security. (Just surrender the blade, keep the handle, and use a replacement blade when you get home.) With this blade pack, now you are covered!
WildCard knife's blade has a hardened steel edge, built to last. In the event you dull the edge, the patent-pending FlyOff™ technology and these replacement blades make it easily replaceable.
See the WildCard knife's product manual that came with your original knife for more information, or go here for videos explaining how to open, close, attach, and remove your new blades.
