That description is only lore-based, as far as it is described in all SAO media. And as Gsimenas said...

...the series is only loosely based on the myths, so there's no guarantee that Excaliber has the same effects as in the original legend.

On a side note, Kirito has used it, but only in a secondary appearance. That was when he went "you shall not pass" on that clearer guild so the Sleeping Knights could get a rematch with the Four-Armed Giant. No description on Excaliber's capabilities was noted, and had there been such an effect, the next day's news would have reflected it (just as Kirito introduced his Dual Skills ability).

Also, "cutting through one's weapons" would either be a remake of Demonic Sword Gram or Kirito utilizing his Arms Blast (outside system skill). If such a remade effect was implemented into Excaliber, then anyone with a high enough One-Handed Sword Skill should easily invoke that effect.

However, I can't say much about the Sugou vs Kirito fight, since Sugou lost his administrative powers (and thus his "cheated" levels) when Kirito set Sugou's authoritative status to Level 1 (probably the level of a standard player. As for what the authoritative level of an admin/GM, I have no idea).

And... weapons do not carry an elemental element. As far as I know, only Sword Skills do.
