May be heresy to bring a Wenger Swiss to the party, but I like my 84mm model with the usual SAK features, plus corkscrew, saw, reamer, small blade, and LOCKING main blade, partially serrated. No need for scissors, as I EDC a Rambler (think Classic with Phillips/bottle opener) on my keychain. I have a bunch of SAKS, but the Wenger is the one I carry on non-office days - for those it's one of the Alox models.
