I remember the exact reason for my carrying 2, one clipped in each front pocket. A stuck right hand and a left hand that couldn't reach the knife clipped onto the right pocket. I needed that knife to cut the serpentine belt my right hand was stuck in.

Ouch. Glad you got out of that situation okay. I would probably do the same if that had happened to me. I generally only carry one pocketknife but if I am at work & wearing my tools I usually have a pocketknife on me & a razor knife in my pouch. Depending on what I am doing a Malco duct knife is either in my pouch or nearby.
