Leon, you are absolutely right. Some people, for whatever reason, just never get the point of being specific. There is a much relations ship of knife to a sword as there is a chisel to a jack hammer. Just heard on the TV, one news stations said they found a blasting cap in the luggage, another said they found a stick of dynamite. Exactly what I would expect from reporters who usually have little science or technical knowledge in any field. I think you could (should) expect a little higher standard of comments in a technical newsgroup.
