I know this is not news, neither it will "heat or cool" the situation, but i would like to mention it, if you don't mind.
In a precious old book that i am lucky to have

,dedicated to the edged weapons collection of the Viscount of Pindela, the introduction covers the evolution of the Portuguese (Peninsular) sword.
At the X century stage, the author (Alfredo Guimarães) reminds us the general form of the cross (guard) that swords were developing since the carolingian cicle, enlarging and later stabilizing, giving symbolic character to the insignia of western christian knights and promoting, in a significant manner, their baptism (1).
In a footnote:
(1) " El nombre que se daba a la espada en el bautismo, lo guardaba toda la vida. La de Carlomagno se llamaba
Joyeuse, la de Roldan,
Aurandal, la de Renato,
Flambaut, la de Oliveros,
Haute claire, la que el Cid conquistó alo rey moro de Valencia se llamaba
Tizona, y la que obtuvo del Conde de Barcelona,
Collada. Asi eran particularisadas" -
Pompeyo Gener
(Pompeyo Gener seems to be a Spanish authority in edged weapons)
