The problem is that it's not established. Assuming the audience knows he has a pocketknife because some kids carried them around when they were younger is not a good idea. Never assume the audience knows something that you haven't hinted at. It'd be like suddenly revealing his a black belt in karate because kids sometimes take karate when they're younger, it doesn't really work and seems sudden.
