In addition to those above, I am trying to trace the origins of these, which may be tourist blades

:
These seem to be the 銅門, Hualien made Aboriginal blades mixed with some sickle-like 開山刀 in the mix. It would seem the Aboriginal blades give a good account of themselves as "machetes". I myself have tested mine out - not bad! Most Han Taiwanese use 開山刀 for brush clearing like a machete. It is also commonly used in Guangdong and Fujian where the handcrafts of making such tools is also dying... ironically while the villagers in both areas prefer the well-made, quality tools of old master craftsmen... very few young apprentices are to be found.
