"Blame it on his interest in knives "
I always carried a knife in elementary school, I shared a big interest in fighting knives with my fellow soldiers (American and foreign), I always have at least two knives on me as an adult, and I belong to two knife forums.
I hope there isn't some new trend to start attacking the natural male interest in knives.
It's one thing to own or collect knives, but also having a bit of a fascination in stabbing someone (not in self
defense) is something different
