Iron design feature facilitates easier ironing around buttons

A specific groove located along the edge of an iron's heating plate serves a practical purpose for ironing clothing, particularly around buttons. According to experts from the Good Housekeeping Institute, this design feature is intended to facilitate easier maneuvering around buttons without applying direct pressure to them.

Using this groove helps prevent buttons from being crushed or damaged by the hot surface and keeps them from being exposed to excessive temperatures. This feature is especially useful for shirts, where fabric often bunches near the button area, making it difficult to lay the garment flat on an ironing board.
