Just have won by ebay this large navaja folding knife and the paid price was worth a try. It's rather large, when opened it's 18" long (45,7 cm) and to my uneducated eyes it seems to have some age but don't think that it is antique.
I know nearly nothing about navajas so I would be more as happy to read your comments. Here the only picture from the seller. Thank you in advance.
