I think you mixed up here something, both Koummya belong to shayde78, I only commented with my limited knowledge.
But you seems to confirm what I've said. And yes, I think also that the first dagger have a trade blade, like Kubur I would like to see better pictures.
And like you I think that the second piece is a so called tourist dagger, cheaply worked with steel sheet blade.
Better pictures would be really helpful.
