A bottle opener is a simple tool designed to remove the metal caps from bottles, typically those containing beverages like beer or soda. It usually consists of a lever and a sharp edge that can grip the cap, allowing the user to pry it off with minimal effort. Bottle openers come in various shapes and sizes, including handheld models, wall-mounted versions, and multi-tools that combine several functions. These tools can be made from different materials, such as stainless steel, plastic, or wood. Some bottle openers are designed with creative themes or branding, making them popular as gifts or collectibles. They are commonly found in homes, bars, and restaurants, serving as essential items for enjoying bottled drinks.
