As I was saying at the weekend, while ranting to iainjcoleman and my father:
a) "Man attacked with sword" articles get much bigger press coverage than "Man stabbed in street" stories because they're exceptional - knife attacks are the norm, sword attacks are unusual and surprising enough to cause comment.
b) The legislation makes no distinction between "real" swords (sharp) and other kinds of swords (theatrical, training, ornamental), which are blunt.
c) A (sharp) sword is already covered by existing knife laws (fixed blade, longer than a max. limit), and using one to intentionally harm/threaten is already illegal, so no new laws are required.
