Nite Ize DooHickey Key Tool
Featuring a host of useful tools, in a lightweight and compact design, the DooHickey Key Tool from Nite Ize is perfect for having handy on keyrings. A sturdy carabiner clip to one end allows it to be clipped to keys, rucksacks or belt loops for ease of access. A box cutter, bottle opener, wrench (1/4, 5/16, and 3/8), ruler (inches and centimetres), and flathead screwdriver, ensure most jobs can be done with ease.
