Hi, hope someone can enlighten me a little. I have been given what appears to be a very old Pocket Knife. I know nothing about it at all except that it is 3 1/2 Inches long (closed) with 2 blades. One blade is a "normal" pointed end blade and the other has arounded end. Both blades are about 2 1/4 Inches long.
