Toothbrush-style scratch brush with 0.006" Stainless Steel Bristle and a Plywood Handle in a curved design for knuckle protection. The stainless steel bristle, hand-laced with stainless steel wire, remains secure even in wet environments if the wooden handle expands or contracts. Each fill tuft is tied into position by hand, resulting in a superior quality brush with maximum fiber retention. Greater bristle density than staple set brushes. For a finer stainless steel bristle brush see part # 15SS-003.
