Support BladeForums! Paid memberships don't see ads! That's great. I use a similar system except I carry a Bowie knife held in my teeth so I can open boxes REALLY fast it's so cool . For real though I usually carry either a folding knife in my pocket or a fixed blade on my belt. As for carrying a folding knife open in a sheath??? Why folding in the first place!?!?! Each to their own I suppose.
