ftenThere definitely needs to be better education of the limits and uses of the law. For example, context needs to be interpreted through the case of employment of the law. If I was carrying this knife with me, and happened to be carrying drugs on me that were Schedule A in the US, I would be fucked. Now, if I bring this knife into a hardware store and buy some wood to cut, that would be just fine.
It appears that the knife is legal. But I don't know if what he posted is accurate, you might want to get a second opinion from an official source.
