Bone chisel is suitable for contouring jawbones and harvesting autologous bone material. Particularly sharp edges enable usage in very hard-to-reach places. The special curvature of the working ends ensures maximum efficiency and simultaneously allows excellent visual control of the amount of bone harvested. The two outer edges are rounded to minimise trauma, thus avoiding deep indentations. Ergonomic handle for maximum control and transfer of force. The matt handle surface reduces irritating light reflections.
