This makes a great argument for a stockman. Big clip point for general work, small spey for ultrasharp edge, sheepsfoot for precision cutting. Carrying this, you will soon learn which style of blade is most useful in your position and perhaps decide to get a single blade knife at that time.
Knowing what I do now, if I had to choose one simple knife for office work, I might very well go for a small gentleman's wharnecliff. That says a lot for a Spyderco Kiwi with one of the better handle materials, although even the stainless handle looks good. Actually, the Kiwi is so unobtrusive, most people simply won't notice it even when you use it.
