Hi Bill,
If that is the name of your sword, it is really special!
I think the second word may have been mistyped. Should be:
饕餮
It's pronounced Tao1 Tie4 (1st intonation and 4th intonation respectively).
It's a mythical voracious beast that was used as a talisman to ward off evil in ancient China. And it so happened that there were a couple of examples in the San Xing Dui exhibition and I took photos of them.
