yea totally pointless to get rid of knives or guns for that matter.
we have a saying here," guns don't kill people - people kill people."
and "if you outlaw a weapon then only the outlaws will have weapons"
i just don't see the point of outlawing something inanimate. anything can be abused and used improperly. anything can kill,( cars, trees, water, fire, Etc) if we outlawed all of them then where would we be? screwed...
