Key-Bit Keychain Tool
Don’t expect it to help much with larger, more daunting projects, but if you need a particular screwdriver on your keychain the Key-Bit Keychain Tool is the one with which to carry it. The pill-shaped Key-Bit is made of either knurled copper or aluminum and fits most standard 1/4-inch bits. It won’t come apart in your pocket since two neodymium magnets hold the halves together with a separation force of over 6 pounds, and the same magnetic force secures the bit. Includes one Phillips hex bit; anything else, you’ll need to pull from your toolbox.
