The Freer elevator is accepted as an excellent instrument. The shaft, which is held between the thumb and two fingers, is too thin to insure a firm grip; therefore the instrument may rotate or slip. The blunt separator with handle has a standard Freer separating end mounted in a hollow handle which fits well in the palm of the hand and is therefore less likely either to slip or to rotate. It is well balanced; so the surgeon has a sense of what is going on at the operating end. The instrument can be used as a regular submucous separator and is especially well adapted for the elevation of tissues in oral surgery. The instrument is available in 6 and 7 inch (15 and 18 cm.) lengths and is manufactured by the George Pilling Company, Philadelphia.
