I carry a Leatherman Raptor all the time these days, it's very specialized to what I do. When I worked in a lab environment, I carried a different multitool to handle wire cutting/stripping/small screws/etc., even though I usually had a real toolbox a few feet away, it was just handy to have on my person. I've never found the blades on the Swiss Army Knife or the Leatherman-type tools of much use, I prefer a more useable/reliable/agile real blade.
