This was a gift to me- Wait for it---Here it comes ( I do wish people would stop giving me knives !! LOL)Anyhow, this is a Spanish traditional "Navaja" style knife( fighting and utility knife).I don't know much about it at all. The obverse side is stamped stainless and Spain on the blade. Although I enclosed a photo of the manufacturer, I can't make out the stylised script.It has an unusual opening mechanism,too.The brass lever on the top of the knife has to be pushed forward, to either open or close the blade. Any information would be appreciated.
