This is a butterfly-style corkscrew. However, as you can see, the gears are supposed to move both arms up and down in perfect synchronization, but due to damage or wear, the gears are not working properly. One arm moves erratically, resulting in a "Heil Hitler" salute pose. The manufacturer is unknown, but similar products are sold for around 10,000 yen, suggesting it's a well-made, high-quality item. How about it as an inappropriate joke item or a decorative piece?
