Where did this unstamped lever lock stiletto originate?

[WindyCity4Life]

Good morning Knife Fam, so I bought this lever lock stiletto switch blade from a flea market yesterday for $20. It opens like a champ, weighs like a quality knife and really just seems to be of real quality material. I believe the handle is some sort of horn or possibly some quality acrylic. Honestly, besides a few scratches, it seems to be of such high quality, yet it has no manufacturer/country of origin stamp. Has anyone ever seen one of these before, and know where it originated from? Maybe it’s just a Chinese switchblade of actual quality, but I’m dying to see where it came from. I’m not expecting it to be a $1,000 find or anything, I just like to know the history of my knives. Anyways, hope everyone is doing well and have a great Sunday!

Looks like an Asian copy of the Italian Leverletto.
