Hello Chris. I am also very happy being able to talk to you. Also I am very happy that my site you like. Recognition from your site a lot to me.
As you probably noticed, in my previous post ruled out the Spanish origin of this knife. So I think in any case. I have not seen in the source texts of Navajas anything like it. I hope you are able to confirm my suspicions.
Knife does not belong to me. Maybe soon I'll have more pictures and further details about it - then be supplemented topic. I'm thinking ... maybe this knife is much older? I've seen similar structurally knives from Roman times. As correctly noted by Chris, the design of this knife is very simple and well known for a long time. It is difficult to definitely rule anything in this matter ...
Pozdrawiam serdecznie
