when you think about it, any weapon can be seen as arabian style, even the Bec or poleaxes.
all cultures used a wide variation of weapons, there was no "Standerd" except in the most disiplined/traditional/advanced/wealthy armies (IE anicent rome, and even then, there was some variation) its safe to say that the saracens/arabians used some form of poleaxes, long mauls, awlpikes and spears
add to the fact that, besides the most isolated cultures, people interacted with each other, they traded, and mingled and fought, those cultures clash, and ideas or styles are mixed togther, especially in the middle east, with it being the center of trade and the melting pot of the world at the time.
so when you think about it, im willingly to bet there were plenty of arabs carrying german poleaxe's. it might not have been called a german poleaxe, but it was shaped like one and functioned like one
