what to look for, here is another example from the Oriental Arms website.
Polish/Slovak knife "This hunting knife is coming from Poland, from the Tatra mountain region in the border of Poland and Slovakia. It is probably late 19 or early 20 C. Finely forged blade 6 inches long with clipped spine and filled back. Very nice grained wood grip with brass mounts and three prongs pommel. Total length 10 ½ inches. Very good condition. Good age patina on the blade. No scabbard."
