OK HERES ANOTHER PUZZLE... WHAT IS THIS....ON THE LEFT SHOWING TWO FACES OF A SWORD...?

On second thoughts I realize I cannot leave it as a simple question since it carries the almost visible description Pallasch!! Having said that what is the relationship with Pallasch and Nimcha? Is the name from Pala(Turkish) or is it simply a result of a continuous morphing nature of whats in a word?... Is it Venitian, Genoan or Italian? The blade is hugely broad and clearly for chopping and slashing. Has the style moved through the Med to such countries as Morocco with seagoing nations, Pirates, merchants or how ...? if this is the case...how did the form slide down the Red Sea or across the desert to the Indian Ocean? Somehow this form has affected several distinctly different regions...and beyond...
What about the second picture with the sword with brasswork on the hilt?
