Where Can I Buy Something To Protect Myself (School Related)?

i guess you could hide a knife and keep it with you, i collect knives and i suggest just a small erfly knife and dont pull it out unless he pulls a weapon, if he wants to fight go fist to fist, if you pull the first knife it could mean jail time for you i would not suggest bringing a knife to school though it could also mean jail time if you get caught with it at all
