Circa 1888-1927. Marked Krusius Brothers Germany on one side of the tang and KB extra with a circle around it on the other side. The blades are tight and the springs are strong. Does not appear to have been used. The blades are full and have a mirror polish finish. There are a few small spots of rust. In wonderful condition for its age. No chips or cracks in the pearl. Comes in a soft pouch.
