Seems to me that we are once again moving into the morass of name game:-)) 
 
But in addition of search engines we are talking about  a common language,  
 We can make it misleading or informative, we can in a single word give a general idea of "what we are talking about", we can attribute weapon's origin or its place of habitation.  
 
Or we can invent a new, wrong, name, and create a non-existing entity ( Karud becoming  a "not-Pesh Kabz) Or assign a name belonging to a different class of objects altogether and lose the specificity of the object in question ( Kris is a small Flamberge). 
 
 Here is an example of parallel development I was talking about: a Central-European Kord or Bauernwehr flanked by two Afghani Khybers.  The blades are virtually interchangeable, but the origins and the dating cannot be farther apart.
