Thanks for the input guys. I plan on upgrading my Leatherman to a Charge soon and it will go from my pocket to my belt. I'll keep my little (its actually 1.5") ceramic for quick access in my pants pocket (I wear dress slacks for work). I'll stick with the folder in my knapsack. I usually keep my PPK in my car, as I don't have any place to conceal it with my normal 'at work' garb, and I am hesitant to leave it unattended in my knapsack. I do bring it in when I am working late as my office isn't in the best of neighborhoods.

I'll leave the fixed blade out - I've never actually had a use for one in an urban setting and really can't foresee any situation where I'd need one. I do carry one in my car kit though.
