We all have that friend -- the one you can always ask for a sticking plaster, safety pin or paracetamol in the event of a small emergency. Asking for a screwdriver to, say, repair a pair of glasses, on the other hand, can be a bit of a crapshoot.
If Swiss Army knives aren't really your thing, or if you just like to have as many tools about your person as humanly possible, there's a solution for those of luscious locks can save you in a pinch: the multi-tool hair-clip.
Created by Israel-based Yaacov Goldberg, with the original idea of holding a yarmulke in place, the stainless steel Leatherdo clips pack in six tools -- seven if you count holding back your hair. A serrated edge on one side allows you to cut things, while the other side has a small, four-centimetre ruler. On the large end, a flat edge works as a screwdriver, and the underside of the clip tapers into an eyeglass screwdriver.
Finally, the large end also doubles as a hex wrench and trolley coin for supermarket trolleys. OK, so maybe it won't be performing heavy-duty tasks -- but we can think of a variety of scenarios in which it could be really useful.
