The AI tells me it’s the Opinel of Piedmont and that the company still exists. It dates it to the late ’80s and ’90s. But the AI lies more than a politician…The question would probably be answered better in the Traditional Forum

It looks like a version of a Piemontese (Piedmontese) pattern. There is a currently made version of this knife although it has wood instead of plastic scales. It appears to be similar to the Opinel, with a ring lock.
As to age, I couldn't tell you. I can't imagine it would be worth a lot as there are countless similar knives that are very inexpensive. These types of knives are very common throughout Italy, Spain, Portugal and France. The question to ask, what is it worth to you?
