Knives are not allowed at my son's school. and honestly, I do not think he is mature enough, or perhaps think HIS friends are mature enough for to be on him.
His reasoning skills are such that I don't think his 1st, 2nd, or even 3rd possible course of action would be to whip out a SAK and cut something. Possibly some scissors to cut something. I was going to get him a boy scout knife or SAK at Christmas or next summer.
