What is Aegishlash's design based on?

And don’t just say “It’s based on Excalibur (or whatever sword or culture)” I want a detailed response on the design. Also try not to say “It looks cool so there doesn’t need to be some complicated backstory of some culture’s history”.

Edit: A downvote, a comment about what more could I want from a sword and shield, and a 1 minute copy-pasted short answer from the Bulbapedia page I read before asking. Now all that’s missing is a flag (JK, this is a serious question)Edit 2: After acknowledging -1 votes I get +1. lolEdit 3: I gave BA but if there are anyone who can explain what these circles on the shield mean or anything it would be appreciated

Aegislashappears to be based on a possessedsword and shield. Its disposition to sense an owner’s potential as leaders and kings, seems to draw inspiration from the ideas of mythical swords of European legend, chieflyExcalibur.

Aegislashis a combination of Aegis (Zeus’s shield in Greek mythology) and slash.Gillguard may be a combination of Gilgamesh or gild (to cover with a layer of gold), 斬る kiru (to slay with a blade) or kill, and guard.
