i guess my favorite would be my leatherman skeletool. i used it all the time at work, cutting open buckets, poking holes in buckets. or using the screwdriver for license plates, and the pliers for antenna's or anything else that comes to mind. i tend to carry it everywhere, i've bought other multi tools and they seem to not be able to replace it, even with the other tools the others might have. the knife on it is sharp, easy to open and close, i love the way it looks as well. i'll also usually carry a pocket knife or whatever one i'm in the mood for at the moment, but the skeletool i tend to use the knife on that more often. i'd love to have a knife with that blade look to it.
