The tang stamp has " ZIPPO BRADFORD PA.  " with " STAINLES " on the pile side. The knife is in good functional condition. ZIPPO knives are still produced but, I have no idea when this one was produced. It looks clean between the liners. I believe it may have been carried due to small scratches and pocket wear. It snaps firmly into the open locked position with a slight blade play. It has a functional blade with no edge dings and it is sharp . Please study photos they are part of the description. The face has a Red logo with " Tenasco Inc. " over " Promotional Products ". The knife is 2 1/2 inches long when closed.
