As I mentioned in another post somewhere, I've never had much use for the mini-tool I bought 10 years ago, or any other. They are too limited. Even if you have the allen key or whatever you need in it at any given time, they tend to be in awkward positions that are difficult and sometimes impossible to use in real life when you actually need it. Much better, I think, to get a mini Allen key set, and whatever other specific tools you need, plus a good Swiss Army knife.
