We’re not sure the world needs another utility knife, but this model from Nack Products piqued our interest. 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 back out in one of six cutting positions.
Invented in Canada, the Nack knife features a removable cartridge that’s factory-loaded with 15 blades — that’s 30 cutting edges before you have to replace the cartridge. Nack makes two version of their knife: one is black with a soft grip, and the other is made of metal and carries the additional title of Pro.
The Nack seems to be available only in the US and Canada, and there aren’t a whole lot of vendors selling it in those countries either. If you do find someone to sell you a Nack knife, it looks like the soft-gripped version will run you $16 while the Pro metal will cost you $20. Replacement cartridges cost $6, or a twin-pack will cost $12 and you get a free belt holster. Yippee Ki Yay!
