Boardwalk Empire knife sighting

[crom]

Been catching this in reruns, so I apologize if this was mentioned already on the boards. Most episodes show some sort of sticker but two that caught my attention recently were a WW1 era brass knuckle duster trench knife and what appeared to be a Schrade Sharp Finger. The knuckle duster was being concealed in a guy's boot and the Sharp Finger was used on a prostitute. Decent show so far as well.
