Why not go the whole hog. Let's ban forks in case someone inadvertently puts one through their foot, spades in case of amputation of toes, rakes in case someone steps on one and hits themselves in the face, garden lines in case somebody trips up, and hoses likewise. Let's ban canes in case anyone bends down and takes their eye out, bonfires in case someone gets a blister etc. etc. etc.
Life is never without risk, and everyone needs to be responsible for their own actions, and take reasonable care not to injure themselves or anyone else.
