NEW 7-PACK NACK UTILITY KNIFE CARTRIDGES - 210 CUTTTING BLADES - FREE SHIPPING

Beautiful, polished stones You can't use your Nack if you don't have the blades
The Nack knife may be one of the best improvements ever made to a tool.  By utilizing a cartridge instead of a single blade, a utility knife becomes 15 knives within virtually the same amount of space.  Instead of taking apart your knife to flip or change the blade when it gets dull, with the Nack knife you retract the blade, rotate the end cap, and slide a fresh blade in place in a matter of seconds.  When those 15 blades have been used, you have another 15 blade edges hidden and ready to go in a couple of minutes, it's no wonder that people who have used it never want to go back.  But hey, just like any knife, eventually the blades need replaced.  For one blade, it's easy – rotate the handle.  To get 30 new blades, you need to replace the cartridge. It takes minutes, then you're back in business with 30 fresh blades that last a long time (in my case, 6 months or longer).  In the home, on the job, at the farm,  in the field - Nack.  Always sharp, always ready.
