A lovely type 3 Falchion, Flemish, ca. 14th century, housed at the Musée de l’Armée.

In the left photo, it’s worth noting that the edge of this single edged blade is on the right side of the sword, not the left. The tip sweep is concave, and likely a development to let you bind onto an opponent’s blade with that section forcefully to push it aside in sword and buckler fighting. Roland Warzecha did a fair amount of live blade sparring with a reproduction of one of these and that was his conclusion.
