This instrument is designed for the removal of the base of the nasal septum and septal ridges. It has been used by a number of rhinologists with gratifying results. Essentially, the instrument is a Freer chisel to which tiny rounded knobs have been added to protect the sharp corners of the blade. The advantage of this protection are clear—it is practically impossible to injure with it the overlying mucous membrane. The projections at the sides of the blades also make it easier to hold the cutting edge against a narrow projection without slipping, and its use with the blade vertical, as in severing a spur, is facilitated thereby.
