Since about 3 weeks ago, I've been going back and forth between 2 folders for EDC, a Charles Marlowe A5 flipper and a DB Fraley 3 1/2" Torrent flipper.
I carry two by Rick Menefee at all times, the green one is a bit over 3'' and makes it nice for sheeple exposure. The Yellow FP is 4 1/8'' and a real workhorse.
