You are correct: we can compose an endless list of Oriental weapons with the same name and different blades or handles ( Ottoman yataghan is just one example), or with different names and identical construction ( see Van Zonneveld's book of Indonesian weapons).
Most, if not all of it, is due to ethnic or even village traditions.
Early Oriental societies had no regulation patterns. The same blade with different handles could have been a Peshkabz with straight blade ( once again, an example of my magnanimity: a Karud) or an Afridi Choora. Asking why did the knifemakers manufacture Peshkabz with straight blade instead of a recurved one is pointless, akin to asking why some Kris are wavy and some are straight or why Zeibek yataghans have T-like pommel instead of an eared one and integral bolster instead of flimsy hollow brass one.
