I don't know how old it is, but I can tell you it is not brand new, it has just been cleaned. The decoration is made of pure silver wire, this is why it might look new.
No, not brand new. I could be wrong, but this looks very much like a style of passio sumange (toli toli) in high quality silver work being done in the late 20th century, so i would say contemporary. The blade is much older.
