when I had the money for it, I had on my at all times (the fixed blade is gone for now until money returns):
-Busse BOSS jack on belt (fixed blade for batoning firewood and other at home wood tasks)
-BM 710 on pocket (edc use folder - mostly boxes)
-crkt stockman (for fine tasks, food prep etc)
-Leatherman charge (for the pliers and bit kit)
total number of edges = 7. I also carry a kershaw nura 3.5 to hand to people when they ask me for a knife, because I don't trust anyone to use my knives for their own safety (they are sharp) or the knives (edges aren't to be used on glass, ceramics, or steel tables... I've had more than one knife damaged by people in that manner)
Overkill? Maybe. I've also always had the tool I needed on me when I've needed it, which is often.
