Note that there are two brands of "Swiss Army Knife": Victorinox and Wenger. Victorinox is the superior product due to its edge-holding characteristics. Its stainless takes a great edge, easily, and keeps it. If you keep it sharp, you won't need scissors unless you're making doilies or silhouettes. I've had several "Officer's" models, which I like because of the two screwdriver blades, one slothead, the other kind of a one-point phillips, and corkscrew (officers drink wine). Invariably a ski knife is used for binding adjustment, field repairs, and picnicing. So you'll need a good blade of a length appropriate to your expected needs (no fights in the lift line, I hope, but long enough to spread mustard or reach in a pickle jar), tweezers for first aid and fine work, can/bottle opener and corkscrew, and screw driver(s) are the minimum. If you do mountaineering, rope trimming's best done with a serrated blade, which will take you out of the "Swiss Army Knife" class. I tried the new Buck Whittaker, twice, and the steel is just too brittle for field work--great for an edge, though. I broke both driver blades trying to adjust my bindings, using maybe only about 50 lbs. of torque in 10 degree temps. Certainly consider the multitool. There's been plenty of times I've needed pliars for broken zippers, dental work, etc.
