Isn't the Swiss Army knife pictured in the dictionary next to "dull tool?"
The cult of the Swiss Army Knife is right up there with the cult of the Leatherman and the cult of WD-40 in encouraging people to fetishize general-purpose but dull tools. The Leatherman is a bit better than the SAK, but it is nothing like a set of top quality tools, just as WD-40 is both a cleaner and lubricant which means it isn't good at either.
I don't really like Swiss Army knives either many of the features are not very functional, or redundant within the tool itself.
I do have a, non-leatherman brand Leatherman and it's totally great.
It's great because I have it on me when I need it, and that's not going to happen with the rest of my tools, as I'm not bringing an entire tool box on a camping trip, or a bike tour, or traveling around the country.
I mean, ask Aron Ralston what he thinks was a good tool to bring along (other than a freakin' clue on things to do, before going on the types of trips he goes on).
