Ironware Bottle Opener Knocker Wall Hanging It seems this was sold as "Happy Ironware." An opener with a decorative, antique key design made of metal. It has a string, so it can be hung on the wall as a "key to happiness" (with a four-leaf clover-shaped hole). It's also substantial as a knocker. It can also be used as a paperweight or ornament. How about it for a Showa retro interior? Made in Japan It was found while cleaning out my parents' house. There is slight rust on the bottle opener part, but the overall condition is good. It looks both antique and modern! It's large, so it's great for interior decoration.
