Most, if not all, replaceable blade knives share the same common failings. Their blades are thin, narrow, brittle and puny! And if they fold their locking mechanisms are egregiously weak! Now Cold Steel introduces a folding knife with 1.5 mm thick interchangeable blades and has the value of a sufficiently strong locking mechanism. Like our Click-N-Cut knives, it incorporates elements of our strong Tri-Ad lock for superior strength. It comes with a drop point blade and a serrated utility blade. Both blades can be re-sharpened with little effort or discarded and easily replaced. Installing or changing a blade is simple. With the blade open, just depress the lock bar and fold the blade down about 70 and slide it out. Click in a new blade and you're back in business! Simple, economical, and astoundingly practical!
