Hello Tim!
You do have a point about the 'X' symbols on the handle but I have seen geometric paterns on arab/mid-eastern weapons before. The end of the handle reminds me of the end on the daggers of south Iraq, only cruder than normal. I have posted a link to a dagger that used to be on Oriental arms that shows some resmblence to the blade shape on the one I just bought.
