Toothbrush-style scratch brush with 0.003" Brass Bristle and a Plywood Handle in a curved design for knuckle protection. The brass fill material hand-laced with stainless steel wire, remains secure even in wet environments if the wooden handle expands or contracts. Hand-laced brushes are the premium brushes in the industry. 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. This useful brush has a 1 x 10 row configuration, with a 7/16" trim, and a brush face of 1-1/2" x 1/16". Handle length is 7-3/4" x 7/16" wide that tapers to 1/4" wide at brush face. Our 1 row brushes are ideal for reaching narrow confned areas. For a thicker brass bristle brush see part # 11BP.
