Typing this all out is going to make me feel sick, seeing as 30 days ago I didn't even EDC a knife.
Benchmade 943sbk Osborne
Benchmade 176 SOCP
Benchmade 147 Nim Cub II
Benchmade Adamas
Boker+ Newton K-bit (birthday present for a friend)
Buck 285 Bantam
Ontario SP10 Raider Bowie
I'm probably set for life. I used to carry a Kershaw Leek but lost it a while back and never got around to replacing it, so I decided to really make up for it. The BM 943 is my EDC folder, the Adamas will be my outdoors / heavy use folder, the Nim Cub for a good (small) fixed blade, and the Ontario for heavy chopping/outdoor tasks. The Buck is for traveling (ie, when I don't want to worry about the Benchmade being "lost" at an airport or something). The SOCP dagger is just cool and makes for a very good emergency blade.
I'm precariously balancing between "practical" and "obsessive."
