Hi
Tim, did you say Taiwan/Formosa ? Here I am
Well, if this knife was from Taiwan, it would be from the Atayal group whose swords are sharing a very similar shape. Most of the other tribes, mainly in the south of the island, use straight blades.
So yours, Freddy, could be similar in the shape with the Atayal's ones, but it appears to me still very different in many points.
My english not being good enough to explain these differences, I let you compare with the help of the pics I hereafter attached.
These are my Atayal swords, out of their sheath.
Judge by yourself !
Best,
