Golok sword

[David]

I find it interesting that the word "golok" is applied to so many different types of edged weapons. But usually they tend to be shorter an thicker chopping blades (more like a machete). The word itself seems to translate to "machete". This one seem very long and slender to be a golok. Why are blades like this also called golok? Is there some alternative name for this blade as well?
