My current most used is my new Chive. I carry it in my 5th pocket and flip it out anytime its even possibly needed (what's that i hear? a piece of string has nice old Mrs. Smith cornered?!? Lets go sidekick Chive, we'll save her!)
I do have 2 other knives on or near me at a time. My REKAT Pioneer II in a belt sheath, and the Pikuni either on my belt or in my backpack. These do get used, just not as much. These 3 are probably my favorite knives, and are always to be found around me.
I would say that the SuperTool was in this list, 'cept I've lost it, and cannot locate it anywhere. Oh, well, now I'll have to get the SuperTool 200, or more!
P.S.- Melvin-Purvis, am I to understand that outside of work you don't wear pants? lol
