I think they just had one of these knife meet&greets at Ohio State yesterday. It didn't turn out so well for the knife collector.
Be careful how you handle this event.
The greatest survival "tool" that you can give your 13-year old son is some extra training in MATH and ENGLISH. If he can master the "they're, their, there's" of life, and be able to keep his checkbook balanced every day, he will survive better than most people in the world today. Just my $.02!
