A buckle includes a metal component having only a first opening and a second opening. The first opening is defined by a first internal perimeter including a first serrated edge. The second opening is defined by a second internal perimeter including a second serrated edge. The buckle also includes a rust resistant component substantially encasing the metal component. However, the rust resistant component does not encase the first serrated edge or the second serrated edge.
