Here's a pic of a backpocket pouch I got from Ron Ryder. Carries a bigger knife easily (Camillus 23 jack here). I've found if I carry a comb next to the knife it keeps it a bit more centered. The pouch also comes in handy if I want to carry a longer knife in a suit coat breast pocket, typically a 4" Queen utility/slim trapper (I dont like to carry things in suit pants). Oddly, the pouch is perfectly sized for an iphone too.
