Tiny but functional knife
Tiny. About two thirds the size of a key when shut. It will only fit 2 fingers. But that is its raison d'être. Despite that size it is a fully functional knife. Fits discreetly on my keyring and has performed well thus far. Decent action, easy enough to open without nails, but holds shut very well. I feel confident the knife won't open and cut me. Slightly larger alternatives exist at a similar price, the tiny size isn't for everyone.
