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. 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 3 x 7 row configuration, with a 7/16" trim, and a brush face of 1-1/2" x 1/4". Handle length is 7-3/4" x 7/16" wide.
