With most knives you have to open up the knife each time you need a new blade, which is inconvenient. Not so with the Nack. This knife offers convenience, efficiency and safety.

How it works / The factory loaded cartridge of blades is inserted into the knife. A blade is selected by turning the end cap and a sliding button moves the blade into position.  When you need to change the blade, you simply repeat the process - 15 times!!!
