These are the Drop Point Replacement Blades for the Click-N-Cut. 3 Pack. There are three different types of blades for the Cold Steel Click-N-Cut utility knife. The blades are double the thickness of most blades on the market, so they can stand up to the most strenuous cutting, scoring, scraping and gouging tasks you can imagine. 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 "click" into place.
