I'm looking for advice on a small folder that could pass for a key on a keychain. Something maximum two inches folded that would be sharp and preferable with a sharp cutting tip as well (not the old style folding knife rounded-tip.) I don't want a multitool, I don't need a bottle opener or anything else. Just a knife. I'm asking because I find myself in many situations without my pocketknife (you can't take them everywhere on a university, after all) and with no way to get into those annoying indestructible plastic domes all electronics come in these days, or some taped packages with key-resistant tape.
Any suggestions? I did a bit of googling but a "key knife" is apparently a trade term in woodwork and molding.
