ALL Sullivan Combs are manufactured to strict specifications with industry leading designs. Each individual comb tooth is shaped and heat treated to ensure the perfect balance of extreme strength with little bend, yet not brittle to cause breakage. With attention to detail, each tooth is individually placed by hand to assure consistency on every comb. The comb blades are crimp pressed to hold each tooth firmly in place. We do not use glue which can dissolve when exposed to water and adhesive removers. Metal handle.
