Sorry but how can you think of that as a knife, thats a cutter, pretty normal to have one when I was in high school. That one is even a little one. I always have one in my car, I always have one on me at work.
@Exia1987 once my friend needed to cut something and i offered her a foldable cutter which she pointed out was kinda scary of me to keep one lol. i just don't like keeping too much stuff in my pencil case and scissors take up more space
Cutter is pretty normal to have.
Scalpel is weird.
Butterfly knife is probably illegal.
Backwards folding scissors that turn into a knife is cool and also a good way to have a large knife seem normal to have.
