I guess it would depend on your occupation or your typical life situations. Personally, I have never found myself wanting for any of those things in my daily carry. I used to carry a Leatherman (Wave) for a while, but found I rarely used it and it was too heavy and bulky to carry around all the time. It has now been relegated to my carry bag, which is something I usually have handy (in the car) but not on my person.

Maybe it is because I am totally inept with tools that I don't find I need them on my person!
