    Julie, 	Is the graver High Speed Steel  or Carbon Steel? If it is
    high speed steel you may be fracturing it when you quench it during
    the grinding stage. High speed steel is not designed to be cooled as
    rapidly as water will cool it. If it is high speed try using a light
    oil to cool it like olive oil or don't cool it at all. High speed
    steels are designed to retain their hardness at very high
    temperatures. If you use the oil it will take considerably longer to
    reduce its temperature.
