The Hu-Friedy #21B Double-Ended Acorn Burnisher features highly polished stainless steel working ends (3.0 mm and 2.7 mm) designed to condense, smooth, carve, and polish amalgam and composite materials in posterior restorations. The #6 Satin Steel handle features an AlTiN (Aluminum Titanium Nitride) coating that creates an extremely hard, smooth surface resistant to scratching and sticking, while the larger diameter helps reduce hand fatigue during extended use. The acorn-shaped design is particularly effective for creating precise occlusal anatomy and accessing hard-to-reach areas.
