The WEAPON, a Swiss Army Knife - GMAFB!!!
Boys carried swiss army knives from about 5th grade on up when I was in school. Many were Boy Scouts and nobody thought it was unusual. I remember girls had small folding pocket knives in their purses, no one thought of these as weapons, they're knives FGS! In middle and high school the administration was only concerned with kids who carried switch blades. Carrying a switch blade pretty much got you expelled.
