Vtg Medieval Style Knife Dagger Medusa Armor Knight Brass Letter Opener 11"

Up for consideration is a vintage large fixed blade Medieval Style Dagger letter opener? The overall length of the piece is just over 11 inches with blade length of just over 5 inches...there is no cutting edge on the piece which leads me to believe that is was designed possibly as a large letter opener. The blade has not been cleaned if you have any questions or something to share please message me. Please see photos as part of the description. Buyer pays a small shipping fee. Best Regards, Johnny  JohnnyCrystal Est. 1987
