Bone chisel suitable for contouring jawbones and harvesting autologous bone material. Particularly sharp edges enable usage in very hard-to-reach places. Special curvature of the working ends ensures maximum efficiency and allows excellent visual control of the amount of bone harvested. The 2 outer edges are rounded to minimise trauma, thus avoiding deep indentations. Ergonomic handle for maximum control and transfer of force. Matt handle surface reduces irritating light reflections.
