Orcrist

[Elu Ancalime]

These quotes seem to suggest that Orcrist wasn't actually buried with Thorin, but instead just laid on his tomb.

In all seriousness (well...a little humor) what if it fell off?

Its another one of those slip of Tolkiens from transferring information from series to series. My guess is that Tolkien meant it to be placed on his tomb, then rather on his chest. Like was aforestated. He would have meant for whatever was written in The Hobbit to stand, since for one he wrote it first. Perhaps!
