I don't see a multi-tool vs knife as an either or situation. I use both. I have a Leatherman Wave (leather sheath) and I wear it whenever I am not at work. I have some other brand in my briefcase that I take to work. I also have a RSK that I wear at work and at home. The RSK is for all of my knife cutting tasks and the wave is for everything else. Once you get used to having it on your belt, I find that I really miss it when I leave it off for some reason. Just the other day I needed to use the pliers to get a grip on the little bulb in my minimag light to replace it.
