  • Patent number: 4072312
    Abstract: A handle construction for racquets having opposing, flat ball-striking playing faces wherein the handle is of substantially octagonal outline of varying sized opposing surfaces, one pair of which are parallel to the playing faces of the racquet, the size variation between these opposing surfaces and other pairs of opposing surfaces among the composite surfaces of the handle are different to the degree that they are sensorially perceptive by sense of feel transmitted by impression gained only in the hand grip of the player without other observation. The determination of these surfaces involved at one or more of the corners of the handle's sectional outline is intensified to be more acute to the feel than the ordinary corner of a handle of normally octagonal outline of 135.degree.
