I would name my sword after the elvish-name of my long-suffering character in the Return of the Entish Bow RP series,
Andotiruves, which in English means
"The Gatekeeper". The elvish sounds so much more impressive and mysterious.
EDIT: For those who want to come up with a real elvish name instead of depending on the name-generator, there is a pretty good
English-to-Elvish Dictionary here. Ram a couple of good words together and see what you can come up with.
