Looks like Hungarian fokos. They originate from shepherd’s axes, perhaps with avar origins. See:

With their wooden handle they may not look too dangerous but I watched some awesome videos with Hungarians fencing with a sabre in one hand and fokos in the other, moving in a constant swirling motion. The fokos was used to divert the opponents cuts and hook the blade. It looked fierce! Sadly I didn’t manage to find the video again.
