When I see these sorts of things I'm reminded of the type of people who like having guns [1] (or watches rated to 100m when they've never gone on a dive in their life). It's like they're hoping for a chance to use their gadgets. I've honestly never been in, nor expect to be in, a situation in which I'll need some tiny watch link screwdriver that's not going to give me any leverage while I simultaneously also don't have access to a real tool. I mean, what do you expect to happen at Disneyland? The ferris wheel gets stuck and you somehow fix it with your multitool?
I don't think my experience is atypical either. I have had to use tools in an emergency before (loose sense of the word emergency here... just a bike problem on a long ride), but in that cases I had my bike tools in a pouch on my bike, so I really don't understand the appeal of this sort of thing, other than just the novelty factor.
[1]: Guns are fun to shoot or hunt with, I'm not talking about that, I'm talking about the kind of person who has guns for "protection", of which I'm acquainted with a few.
