Exchanging a blade is easy. The handle has a lock bar release, similar to the release on a folding knife. When the lock bar is pressed the blade slides easily out. Keep the lock bar pressed and slide a new blade in and release the lock bar and the blade will â??clickâ?쳌 into place. The Click-N-Cut includes a belt sheath that will hold the knife with one of the blades installed and it has integral pockets for the two remaining extra blades. Extra replacement blades are available separately.
