For the last few years, my only key chain tool has been the Swiss Tech utili-key. HERE is my old review from 2008. I absolutely love the utili-key. It took me a while to start frequently using it, meaning, I would forget it was there in my pocket. Of course, in a way, that's what I was hoping for. Now I find myself using it a few times a week.
As for the Micro 6 in 1, I got this tool as a belated birthday present a few months ago. Does it live up to the high bar of the utili-key? Well, the short answer is that I'm still not sure.

All of the uses seem to work adequately. Keep in mind the retail price on this is under $10, so I don't have huge expectations. For this things I've used it on, it's fine. Sure, there are other tools that have these features and work better, but not many have this good of a balance between small size and usefulness.
I've only had this in my pocket for a few months now. I haven't used it all that much, but I plan on giving it more time to prove its place on my keyring.
Update: In the last few days, the arms have really seemed to loosen up. In fact, it's fallen off my key chain a few times now. For the time being, at least, I'm going to keep it on the bench until I figure out what to do with it.
