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 that allows the user to turn the wheel. There are various types of can openers, including manual and electric versions, each serving the same basic purpose. Using a can opener is straightforward: the user positions the tool on the can's edge, clamps it down, and turns the handle to cut through the lid. This tool is essential for accessing canned foods, which are often sealed for preservation. Common canned items include vegetables, fruits, and soups.
