very good writeup. knives are alot more common than guns and can be made from just about anything to include toilet paper. very dangerous weapons to be aware of but also as important to know how to safely handle one.
i still have my very first pocketknife my dad ever bought me when i was getting trained to use on in cub scouts. its a sak thats over 20+ years old.
