The Met Museum avoids using dagger names except for the katar in their book "Islamic Arms and Armor in The Metropolitan Museum of Art", David G. Alexander,
Metropolitan Museum of Art, 2015, I guess that is one way to solve the name situation. Jambiya, kard and khanjar are all described was "dagger". Just remove all "foreign terms"....humm....like that is so much better than including all of those pesky "foreign terms" with understandable explanations. The term "katar" is used once along with other possible names but the image has "punch dagger" as the description.
In keeping with the intention that this publication should be intelligible to the general reader as well as the specialist, foreign terms have been kept to a minimum.
