The essential answer, IMO, is: any one with a saw. The very excellent Vic saws amplify the power of these tools a hundredfold.

The oversize Soldier/Trekker series can do a great deal of practical work. Great saw, decent locking blade with thumbhole (one-handed open, or open with heavy mitts), and an oversize screwdriver that takes a lot of the prybar abuse away from the blade. Plus the usual suspects, all of which work quite well. My only bug is that I don't find the shape comfortable for pocket carry; a sheath is best.

I would also seriously consider the Farmer (or its cousin with the extra pruning blade [Pioneer Harvester]). These are much stronger than the standard-size, nylon-handled SAK. The blades don't lock, but the springs are quite strong (locks are useful, but absolute trust in them is naive). They have the oversize screwdriver/prybar and a highly functional awl. And of course, both have that wonderful saw.
