Why are people so darn terrified of knives? Are they simply scared of the unknown, or is there a legitimate reason for all the controversy and widespread banning of these tools? Hammers and writing utensils can just as easily be used as a weapon You know those tiny little hammers that are just a bit bigger than your palm? Looks like a tool, right? That can easily be used as a covert impact weapon capable of delivering devastating blunt trauma. Those $1 bic ballpoint pens could just as easily be used as a kubotan or spike. That's where "the pen is mightier than the sword" comes from. /sarcasm Knives are generally banned in schools, but nobody bats an eye to a kid carrying a pair of scissors - which are just two knives stuck together with a screw. One can literally sharpen a pair of scissors in less than 10 minutes using concrete such that the blade has an edge that's able to slice through paper without tearing. A knife is used for opening boxes and cutting paper. Its ability to be used as a weapon shouldn't be its defining characteristic. I swear, people treat knives like they're volatile explosives or something. I'd like to hear your thoughts on this, especially if it differs from mine.
