I use this one for work, where the weight isn't a problem, and it's the best tool I've ever used. (before Swisstools some Leatherman and SOG tools)If you like lightweight I would recommend the Spirit, which is what I also use for casual/travel. This one is the same high quality just heavier with a more solid build. (and I personally love the horizontal leather sheath which looks very 'non-knifey')
