I actually saw the thread in question, but couldn't find any markings on either of the U-keys I owned. Does this mean they're fakes? (Image removed from quote.)
Okay, I finally "discovered" a work-around for opening the tool without shedding blood: hold the sharp part with a shirt or something. Works like a charm, both for grip and (if you have a thick shirt) protection from the edge.This may only present a problem since mine is extremely, incredibly tight. Much more so than the first one I've handled. It's not necessarily a bad thing, as I can be absolutely sure it won't fall off my key ring...
I have never carried my utili-key. I should really give it a go.
