Karud: the weapon that did not exist:-)

Correct. I just chose the most direct and believable connections.
Also, "dagger" was associated with "daca", presumably a name for Dacian dagger, although all known Dacian daggers were crooked, and rightfully belong to the same group as "sica" ( sicarii used them), which likely stems from the Hebrew " sakin", knife.

Words mutate: Persian khanjar becomes Georgian khanjali, and from there Russian kinzhal. In Russian usage, any fighting double-edged short bladed weapon is kinzhal: thus, in Russian books one can see " kinzhal bichwa", " kinzhal kris", " kinzhal katar", and even "kinzhal kinzhal":-) etc. Some less picky authors apply it to single-edged implements as well: " kinzhal kukri", " kinzhal karud" etc.

Come to think of it, a large proportion of names for a short-bladed weapon in all languages is just a local moniker or a derivative of "knife".
