'Red Special' sword

I, the owner of this image, have released this image into the public domain.

A few months ago, I received this piece of beauty from a friend of mine. I asked him what type of a sword this was, but all he said was that it's Chinese. It's still beautiful, and it cuts well, too. If you know what it is, tell me.

UPDATE: Thanks to I've found that this sword is known as a Daab Song Mue, which involve use with the Thai Martial Art of Krabi-Krabong. Unfortunately, it's part of a set of two, the other which I don't have. Due to the curved shape of the blade, other styles (Katana) may be substituted in my case.
