As you all likely know, the various forms of "weed eaters" (both the ones with the monofilament lines and the ones with the hard plastic blades) can cut through tough weeds and fibrous plant materials with ease. I would like both those whom are familiar with law enforcement and legal knowledge and everyone else to comment on this: In an emergency for home self protection or while outside of the home, would a decent weed-eater make a good self protection device and what would any legal implications be for the person protecting themself and their family with one?
