A "double-handle" refers to a type of handle that features two grips, allowing for better control and stability when lifting or carrying an object. This design is commonly found on items like buckets, suitcases, and toolboxes, where the added support helps distribute weight evenly. In addition to improving grip, double-handles can enhance safety by reducing the risk of dropping or spilling contents. They are particularly useful in situations where a single handle may not provide enough leverage, making tasks easier and more efficient for users.
