They use that argument for guns.
But this gun is designed for killing! It's military style. Yeah, if you subscribe to that logic (which I don't).
That logic is nonsense with a knife. A knife is a knife is a knife, regardless of shape or 'intended purpose'.
These 'combat knives' you hear about, are clearly not useful in a fighting situation. They are heavy, often have a saw on the back of them and really are just camping knives with a fancy name.
Lets ban hands. A hand is way more dangerous than a knife. Hands are everywhere and no one has been conditioned to be fearful of a hand. Hands are friendly right?
What if I approach you with soft eyes and a smile, give you a left handed wave, up high, say hello, relax you, use that left hand, thumb and index finger to gouge your eyes, your hands go straight to your face instinctively, come in with my right hand, crush your windpipe with my right hand, you can't scream (ability to inhale and exhale is gone) and you suffocate to death.
Yeah, hands are next to go.
This is nonsense.
