Given by angels not easily justified its not a man-made, or deserves EX. Gram is given by Odin himself to Sigurd ancestor and its not even goes EX by default. Excalibur itself, despite crafted under fairy hand, not instantly having EX.

Nasu already made it in Extella that is the main reason why they're not that strong, and its already established since FSN which is why stronger heroes are often old, fictional, archaic heroes instead of new, modern heroes with real-life accomplishments. Paladins became weaker as their real histories fame greatly weakens their fictional mysteries aspect.

Saying that having real-life counterparts is something 'big' is like ignoring fact we have Gilgamesh, Karna, Sigurd, Siegfried and Hercules. How you explain that?

You're pushing your headcanon too far by saying Excalibur will easily broken by Durandal. Excalibur under Nasuverse is a Divine Construct that it'll took more effort than 'sword known to be sharp' to crush it.
