"PHILCO" JAR OPENER Pat'd Sept 1922 Metal Gripper Jaws! - eBay (item 310081429692 end time Sep-10-08 19:42:42 PDT)
This vintage bottle and jar opener is made of metal marked, "Philco" and "Pat'd Sept 1922" and "Conneaut, Ohio." The spring in the hinge keeps it open until you close it. The handles are dark red.
It's has teeth in the ring and teeth on two prongs. Perhaps the three upright parts on one side are for prying off a lid. The gripper jaws make a perfect circle well before you completely close the handles, so there's good gripping power here.
