What is a "tin opener"?

A tin opener is a handheld kitchen tool used for opening cans or tins. It typically consists of a handle with a rotating wheel or blade attached to a cutting mechanism. To use a tin opener, you place the cutting wheel or blade against the edge of the can lid and then rotate the handle, which causes the blade to puncture and cut through the lid, allowing it to be removed. Tin openers come in various designs, including manual handheld models and electric versions, each offering different features and benefits.
