3 x 7 Row Scratch Brush with Horse Hair Bristle and Plywood Handle

All-purpose toothbrush-style scratch brush, designed with a bend for knuckle protection. Heavy duty anti-static horse hair bristle, in a 3 X 7 row configuration, with a 7/16" trim, and a brush face of 1-3/8" x 1/4", with a strong, static-neutral plywood handle, makes a great tool that can be used for a wide variety of applications including board rework and cleanup.
