Foilist, the Executive was my first 74mm SAK and it's a really great compromise between the 58mm and the larger SAKs. As a secondary, I think the Exec is great, and for a "white collar" EDC, it could do as a primary carry knife. One note - Exec prices vary wildly so shop around. They can be had for <$25 NIB is you look hard.
Still, if you want more versatility than a slipjoint, I agree that the Compact is a nice full-size Vic that covers all the major urban needs (no woodsaw, though). If you can do without scissors, tweezers, and toothpick, thealox Cadet (84mm) is a slim two layers yet has all the 'classic' SAK tools on board. You can choose between the Cadet (large blade, can opener/small screwdriver, flathead screwdriver/cap lifter, and nail file/medium Philips screwdriver) and the Cadet II, with a small blade in place of the nail file/Philips.
