WWII Theater Stiletto Dagger Knife OSS?

This is an unusual WWII Theater Stiletto from my collection. Looks almost like an OSS piece. Stiletto measures 9 1/2" overall with a wicked armor-piercing 6" blade. Handle is made of brass riveted tropical wood scales. Double brass crossguard formed to fit perfectly in hand. Handle has nice weight and feel to it. Nice patina. Piece is in like new condition. Very unusual and covert weapon.
