Here are a few suggestions:
You may want to check out a Small Classic Sebenza, plain handled or an inlay version. or a Mnandi.
Both are pretty classy looking, and of course the Mnandi is the classier of the 2.
You could then grab a Tradional folder as well. You may want to check out either a nice 70's model of the Case Whittler. A light bone color looks really nice with a dark suit, and you could grab a darker bone handle for your lighter suits.
Or instead of the older Case, you could grab either a Bulldog, or a German Eye brand, either in a stockman or a whittler, and still have a killer blade. (the germans's are my pick over any cases other than the older models.)
Long story short, you could grab either the classic Seb or the Mnandi, + a Case or 2, or a Boker/ German eye or 2 and still be under your price range, or grab a SAK.
Been in a couple of meetings where someone had dropped something small down in their key pad on their Lap top, and the tweezers on the SAK saved the day, and they are very sheeple friendly.
Or, another really classy smaller clip carry knife you could get to go with your Seb/ Mnandi would be the Spyderco Cricket.
Classy looking, and small enough to double as a money clip.
When I wear a suit, I like the Small Seb / SAK cobo myself.
