In the RRR we refer to them as bayonets. Although I had the pleasure of attending the 125th anniversary of the Royal Winnipeg rifles and they have ceremonial skirmishers who follow the aide-memoire from the late 1800's, they refer to their bayonets as swords, well, because they are swords.
Here is a photo of the ceremonial skirmishers, the one in the middle is a ceremonial pioneer.
