The design of bottle openers is diverse to meet the opening needs of different bottle caps. The most common is a manual bottle opener, which is usually made of metal and has a sharp blade and an easy to operate handle. When in use, we only need to insert the blade into the gap between the bottle cap and the bottle body, and then gently twist the handle with force, and the bottle cap can easily come off. This type of bottle opener is easy to operate and convenient to carry, making it an essential item in homes, bars, restaurants, and other places.
