You can make the Greatsword of Artorias if you bring this Souls and Straight Sword Hilt + 10 or Broken Straight Sword +10  to the Giant blacksmith in Anor Lando.

Also you can make the Greatsword of Artorias(cursed) from a normal Straight Sword+10 to the giant blacksmith.

And also the Greatshield of Artorias from a normal Shield +10 to the Giant Blacksmith.

All of these items are pretty nice and usefull if you like Greatswords/shields because the Swords scale with all 4 stats so yea really nice and the shield will block enemy attacks with a status like Bleeding or Poison but one thing they are pretty heavy, hope this helps what you can do with this Soul.
