Why was Excalibur not used near the end of season 2?


I just finished re-watching episode 18 of season 2 of _Sword Art Online_ , and
in the end, Kirito throws Excalibur into the pit and then Shinon catches it
with a spell arrow. Then, once the quest is over, he gets the sword as a gift
from Urðr for saving the land. In the next episodes we don't see him use it.

Why isn't he using it?




In SAO Wikia about
[Excalibur](http://swordartonline.wikia.com/wiki/Holy_Sword_Excalibur), there
is some trivia mentioned, among which:

> Kazuto resolved to never use Excalibur for personal gain as he believed that
> the sword contained the «caliber» of himself and his companions.

As mentioned in the comments and in [Alchemist's
answer](https://anime.stackexchange.com/a/36050/2516), Kirito used the sword
when fighting off the guild to buy Asuna some time.
