Rhoka Sword: Where is it from?

[Atamis]

I have been looking for an answer to where the rhoka sword, name and historically the type of sword it is, came from. I mean I've seen this kind of sword before but this is the closest I've ever been to having it named. I kinda like to know what culture made it and if its really called a rhoka sword or something else. I love this sword design and like making characters that wield it mainly for look but would love to know if there is more to it then what's in its brief description. Does anyone have more insight on this? Thank you

On Golarion, the Rhoka sword comes from the Urdefhan, which are very nasty Native Outsiders of generally Humanoid form that live in the Darklands.

On Earth, Rhoka is a settlement on one of Kenya's rivers in the Coast Province. No idea if it ever had any weapons of this type.
