摘要：An impact instrument for delivering an impulse to an object. The impactinstrument may include an impact surface for contacting the object and an elongatedmember extending from the impact surface that terminates in an end. The elongatedmember may include a grasping region in the vicinity of the end. When the instrument is
grasped within the grasping region, the center of percussion of the instrumentpreferably coincides with the impact surface. The instrument may also contain pivotinggrasping member disposed on the elongated member. A cavity is preferably formedbetween the grasping member and the elongated member and may contain
compressible material. The grasping member may rigidly contact the elongated memberat an ideal pivot point. The grasping member is preferably adapted to pivot with respectto the elongated member at the ideal pivot point. The pivoting of the grasping memberpreferably increases the amount of impulse delivered to an object, decreases vibrationexperienced by the user of the instrument, and reduces counter-rotational forcesimparted from the instrument to the user. The impact instrument may be a hammer, ax,golf club, tennis racket, or similar device.
