A kota knife

[Flavio]

Here is my last purchase: a kota knife. Now, as you see, this one isn't one of the best that you can see on the books, but anyway is quite nice (the price is quite low and not hundreds of dollars!!). These kind of knives are use in some secret social groups among the kota, but in some books knives like mine (not so "beautiful") are considered as currency. What is strange for me, as you can see from the pictures, is that the blade is very thin and so the amount of iron very low for a currency; moreover the engraved surface for me means that it wasn't a mere object of exchange. Also the working is strange: the surface don't seem to be hammered but shows like if some drops of metal were fallen over. So maybe this type of musele is more recent that the beautifulr ones that we can see on books, and perhaps they are copy for "white people"? What do you think about this? There is some of you that have these knives? Could you please tell me if your blade shows some kind of midrib or is completely flat like mine? Thank you
