I rotate dependent on my dress and/or the occasion which knife I have on my body: Emerson mini CQC-7, Rat Cutlery Izula, Muddy Active Duty or Game Warden.
I always have a SAK Farmer in my pocket for the times when pulling out a fixed blade isnt the best decision.
Regardless of whats on my body, living in NYC, whenever I go anywhere my EDC bag comes with me (a Kifaru E&E or an Orvis briefcase) - in there will always be my Muddy Active Duty (if its not on me) or if its on me, my Rat Cutlery RC-3.
Had my bag checked a few times in random subway screenings and the MAD or RC-3 has never been an issue.
Carrying in NYC is a bit weird - the laws are such that I am much better off carrying a sub 3.5" fixed blade (concealed) rather than a locking folder as the laws are clear as day on fixed blades but ridiculously ambiguous on folders (on purpose I'm sure).
Regardless, by law, whatever I carry must be 100% concealed - I cant even keep my Emerson clipped to the inside of my pants pocket bc LEO specifically look for the clip - been stopped before for a clip showing but it was my EDC flashlight
When I'm at our place in the Catskills, depending on my mood, I either EDC on my belt my MAD, GW, or RC-3 - still with my SAK in my pocket.
