Just a reminder: Caledfwlch, Caliburnus, and Excalibur are, originally, all the same sword (just in diffrent language)... and it you go by Le Morte D'Arthur, neither is the Sword in the Stone but the one from the Lady of the Lake. Technically, Caladbolg is a completely different sword.

Side note, looking this up, I found that Caladbolg means "hard cleft" or "hard blade", same as what Caledfwlch means. So you can headcanon that the Lady of the Lake gave Arthur a hand-me-down.
