The term 'blunt-edged sword' can be summarized as an epee, which is a type of fencing sword with a triangular cross-section and a blunted tip. It is used in the sport of fencing and is designed to score points by making contact with the opponent's body. The epee is the heaviest of the three weapons used in fencing, and its blade is flexible enough to bend when it comes into contact with an opponent's blade.
