Now I'm a die-hard knife enthusiast. And I strongly believe that people should freely exercise their legal knife rights. But I believe that PLAYING with ones knife in public is really crossing the line and a BIG MISTAKE.
If I saw a person walking down the street repeatedly flicking a knife open, I might likely think he was deranged and I would strongly consider calling the cops. After all, I don't know the guy, I don't know what his intentions are, and walking around in PUBLIC repeatedly flicking a knife open makes no rational sense to me. Just as if I saw a person walking down the street carrying a gun in their hand, I would have to ask myself "What if he attacks someone on the street and I didn't do anything to try and stop him like simply calling the cops?".
Remember, how YOU perceive yourself isn't necessarily the same way that the rest of the world perceives you. YOU know that you're a good guy who has no intentions of harming anyone, but others who see you don't know this. And it doesn't cost them a dime to call the cops on you.
"911 what is your emergency"
"There's a man walking down the street playing with a knife!"
I GARUNTEE that this is something the cops would take a strong interest in. And when they respond to a call of a man "walking the street playing with a knife", don't be a bit surprised if they meet you with guns drawn and pointed at you. And if that happens, it only takes one little mistake, on your part or the cop, for you to get shot. Remember, like I said, THEY DON'T KNOW YOU. For all the cops know you are a deranged lunatic armed with a knife who won't hesitate to try and kill them.
I strongly suggest that if people want to play with their knives that they do it at home.
