I believe this is a modern made Atayal type blade. It was used for fighting (and headhunting), survival out in the wilderness, etc. It’s a good solid blade, legit ferrule/bolster(?), rattan handle, thick spine, gently curved blade, single bevel, open sheath, and has a good feeling. I got it from the Tung-men (Copper-gate) folks at Hua-lien. I also visited the Atayal museum at Wu-lai. It was very interesting. I was a bit surprised to find that many Yuan Zhu Min are pro-KMT as opposed to DPP - somewhat ironic... but let's leave politics aside. I learned quite a bit today. They had a good collection of blades and spears.
