That brings back of flood of memories of a VERY similar sword that my grandfather used to have hanging on the wall. I wish I knew where he got it, or could ask him about it, but unfortunately he's in the pretty late stages of dementia/Alzheimer's right now. I think Tracy is pretty close with the guess about origin. If you do an image search for "Carved wooden sword and sheath" or something along those lines, you'll get several similar pieces. The first few I saw mentioned either Philippines or Vietnam. Likely a common piece found in tourist markets and what not.
