No, but they were before fencing became a sport. Since they no
longer have sharpened edges or tips, they are not considered real
swords, and are called 'Weapons'. Calling a Foil, Epee, or Sabre a
'Sword' in a room full of fencers will only result in a room full
of glares or scoffing.
Fencing swords are not real swords because when they are made,
one thing is kept in mind, the sharpeness of the blade. The blades
are not that sharpening as compared to the real one. After all you
want to use it for home decor purpose and not for cutting or
thrashing.
