You Watch! Somehow or other it will be the knifes fault.... soooo we need knife control im sure it will work, like gun control works. What if EVERY single gun on the planet disappeared instantly. Do you think people will stop killing people? It wont ever happen because people are high functioning animals but animals all the same. People have been killing people since the 1st people. No matter what you ban or try to control people are people... shrugs
