I might be too late for this, but I probably wouldn't get the Micro if I were you. The 2.5" and 3" are both pretty nice offerings, doing what it supposed to.
But the micro is nothing like them--basically it is a non-locking 'friction' folder which has to live in a sheath, and to make the matter worse, the workmanship is subpar and has a horrible blade rub on mine. The ergo is pretty bad, since they didn't bother to chamfer the edges and the handle is thin.
It was peened together, so I can't fix anything unless I want to re-peen the whole thing back together. It could potentially make a cute nice project, but not very desirable as it was.
