So to sum it up I think brass knuckles are illegal everywhere. I'm on my phone so I can't quote but reading the stat from Washington I think my 3inch knife is illegal there wtf! To open you hold it from the side and press down on a certain part and the blade slides up from the other side. It's not mechanical or a switch blade but it basically said any knife that can be extracted without having to physically pull the blade out
Wow. My little pink Kershaw pocket knife with open assist has just made me a criminal! Don't mess with me! I'm a baaaad chica!
