Very old butterfly knife I believe the handle is either bone or ivory and I think the blade has been cut down. The knife was given to me by my father in the early 1960s.
The blade is stamped on one side what looks like Bontgen & Sabin Patent 1500, and on the other side P. METZ Warranted.
The length of the handle is 80mm and the blade length is 40mm. The handle is 13mm wide.
Can anyone help me as to the age etc.
