Hello Stefan,
Not only the blade, but also the hilt with the kitchish red "gem" is shouting: "kitch for unsuspecting tourists!"
You can start just browsing the web and looking at the photos for "koummya dagger." In the photos, you can examine differences in the quality of materials and mostly workmanship.
Better yet, just have a look at the very educative article right on this forum:
