I'm sorry Aurangzeb ,
I'm guessing that this piece is very late 19th-mid 20th C. and meant to be a curio for Westerners on the Grand Tour .
Consider the concept of the blade mechanics ; if the point was made for piercing mail the two rather thin side blades would spread and prevent any sort of deep penetration ; the same effect would also happen with a few layers of fabric .
This dagger may have allegorical or cultural meanings but doubtful that it is a 'user' .
/now , about that copy of Stone's .........
