A can opener is a kitchen tool designed to open metal cans. It typically consists of a rotating cutting wheel that punctures the can's lid and a handle for easy operation. There are various types of can openers, including manual and electric versions, each serving the same purpose but with different levels of effort required. Using a can opener is straightforward: you place the tool on the can's edge, squeeze the handles, and turn the cutting wheel around the lid. This action creates a clean cut, allowing you to safely access the contents inside the can, such as vegetables, soup, or fruit.
