I have two different situations, "office carry" (sub-2.5") and "outside office carry" (anything reasonable goes). For both, I have a small group of frequently carried knives, then a larger group that get carried occasionally but not as often as the others. In general I don't keep any knives that I don't carry at least once in a while.
For office carry there's a core group of two (One-Eyed Jack, Rhino). The V-Toku2 Meerkat, when it comes out, might push its way into this group.
For outside office carry the core group is a little more expansive. Besides the PM2 (in one of several variants) and the Southard, there are also several non-Spydies: the North Arm Skaha 2, the Sebenza, and a number of vintage Benchmades: the Tsunami (700), the AFCK (800), the Dark Star (880) and the Stryker (910). Albeit the AFCK is kind of an honorary Spydie ...
Generally I prefer nonserrated, noncoated blades. I still have some older partially serrated knives that I have sentimental attachment to, but I don't buy them these days except in unusual circumstances.
