Captain's Greatsword's charms

[Captain's Greatsword]

The Captain's Greatsword's description mentions the following: " ...A thin chain hangs from the hilt, although the charms that should be attached to it appear to have gone missing."
Are these charms retrievable and can they be attached to the sword again or is this just flavor text?
