I have a sincere question related to keychain tools... I've carried a couple of various tools on my keychains for years. One is a NiteIze Doohickey and the other is a generic small button shaped LED light. I carry a fairly normal compliment of EDC stuff in my pockets (small SAK, Fenix light, etc.). I'm pretty sure I could count on one hand the number of times I've ever needed to actually "use" a keychain tool. In fact, one time I made a point out of opening a box with my Doohickey just so I could say I've used it. I see all these exotic Atwood tools and the like here, all manner of mini-pry bars and so forth. I'm really wondering how much these get used in real world practice. Please don't get me wrong, I think they look really cool and are interesting in their form (almost like art in some respects), but what about actual "utility"? So, to my question... Do you actually "use" your keychain tool on a frequent basis, or is it really more of a novelty? Thanks (and I mean no disrespect by my question).
