Hi,
I just realized how hard it is to find good samples of these knives online
. They come from a very small area and they have a very specific style and design to them, with some variations of course. The main town that produces them is Surmene, so you can also look up Surmene Knife in yoru search. You will see that they still make these knives today, actually very similar looking to your samples as well (other than the handle style and bronze details).
I dont have pictures of my collection readily available but I found some examples online for you just now.
