If you're like me, you always have a knife on hand. But some knives are a little bulky to be carrying in your pocket all the time. Here's one of the handiest compact blades we've ever come across - the Screwpop Utility Knife.
This retractable knife is slim and has a loop to easily attach to your keyring. This nickel-plated knife uses standard utility blades, so it's a snap to have a fresh, sharp blade whenever yiou need one. It also will function as a bottle opener, so this might well be one of the handiest items you'll ever come across.
