Lots of mythical named weapons.

Fictional also has a ton. The ones I immediately hit on were Glamdring and Sting from the Lord of the Rings and Stormbringer from the Elric series by Michael Moorcock.

A little more research came up with this list that hits mythical, historical, fictional, and pop culture weapons.

The first one that came to mind for me was from The Hobbit. You have Sting of course, but then you also have Glamdring and Orcrest.
