Something lightweight that has just the basics- scissors, a main knife, phillips head and flat head screwdriver, a bottle and can opener. Tweezers could be nice too, if it's a SAK, but it's not necessary.
From the ones I can personally recommend you've got a few choices. If we look at SAKs then a Victorinox Super Tinker would be OK but I do prefer the in-line Phillips found on the Explorer. Also look at Wenger with the Evo 16.
Going on to MTs and the LM Juice S2 you listed fits the bill nicely. The LM Fuse is an excellent tool but it's much to large for comfortable pocket carry IMO. Same story with the Gerber MP400, good tool but I wear mine in a belt pouch or keep it in my bag, never a pocket.
