There are some really well thought out posts in this thread. Great job guys.
I've spent a lot of time thinking about this, and will be starting a companion thread. However, for here I've decided I actually want more knives than the "just enough" or even "more than enough". This decision is based upon experience trying to use the wrong tool.
For my lifestyle (I live in the country, periodically drive 2 hours round trip to professional office job three towns away, am starting a small organic farm, am "self preservation" minded, tend to take care of things myself, etc etc.). Basically, I'm an individualist. As such I think I really need:
EDC FOLDER (everywhere everyday): Spyderco Delica4 or Endura4
NECKER/POCKET FIXED: Swamp Rat Warden
WARM WEATHER (LIGHT COVER GARMENT) BELT CARRY FIXED EDC (for going into town): Busse Leaner Meaner or Boss Street
COOL WEATHER BELT CARRY FIXED EDC (going into a "rough area" or further from home): Busse SAR-5
FARM WORK EDC: Swamp Rat RMD
GET HOME BAG (when commuting to the office where I can't wear a fixed blade on my belt): Busse SAR-5 or Busse ASH-1 Skinny
WOODSCRAFT & SURVIVAL: Swamp Rat Vex or RMD + Busse SAR-5 or ASH-1 + Busse NMSFNO or NMFSH or ASHBM
HUNTING: Swamp Rat Vex + Busse ASH-1
FENDING OFF THE ALIEN ZOMBIE INVASION: Busse ASH-1 or Axe Hammer or Tank Buster or TGLB
This will probably change as soon as I hit "submit".
