I found this brass object measure that measures about 1.5 x 4 cm in the back yard of a house built in 1906. The cylindrical end is threaded and the blade end is snapped off or cut with force. There is a rivet connecting the blade end to the cylindrical end and it is possible (although I'm not certain) this could have served as a pivot joint. The pieces don't pivot currently. Neither edge of the blade is sharp although one side is slightly beveled and I can't tell whether this is due to the damage or whether this is the intentional design of the object. I have searched the internet high and low for images of brass objects with various terms without success. Maybe someone has seen one of these before?
