Stamped from a single piece of stainless steel, the Doohickey integrates a flat-head screwdriver, a bottle opener, a box cutter scoring edge, a ruler, and a wrench into a profile that sits flat alongside house keys and car fobs. There are no moving parts, no springs, no hinges, and no pivot points — which means there is nothing to fail.
The stainless steel body resists corrosion even after years of pocket carry, and the tool's small size means it passes TSA screening in most configurations. At roughly $5, the cost-per-year calculation is almost meaningless — this tool will outlast the keyring it hangs from.
Nite Ize provides a limited lifetime warranty against manufacturing defects. The Doohickey will not replace a proper multi-tool for serious tasks, but it fills the gap between having nothing and having to carry a full-sized tool.
For the EDC minimalist who wants basic capability at zero weight penalty, the Doohickey delivers exactly what it promises. Nothing more, nothing less, nothing to break.
