A jar opener, also known as a jar wrench, is a kitchen utensil specifically designed to assist in opening jars and bottles with difficult-to-grip lids. It typically consists of a rubber or plastic grip and a metal band with teeth or ridges that fit around the lid, providing extra leverage and grip to loosen and remove the lid.
Jar openers are particularly beneficial for individuals with limited hand strength, dexterity issues, or arthritis, as they can significantly reduce the effort and discomfort associated with opening jars. They also come in various sizes and shapes to accommodate different jar and bottle sizes and types.
