Vintage Wenger Dog-Leg Can Opener, This is a vintage Wenger from the early 1970's or late 1960's. The can opener is called a dog-leg style due to its shape. It is made so you pierce the can and then rock the leg up and down to cut the metal on the upward cut. There are a couple styles with one having a longer "leg" than this one. I think the longer leg version is older as it does not have the diagram on it as the other one does.
