ABSTRACT:
A metal racket includes a hollow looped head portion having a cross-section lying on a plane perpendicular to a string web held by the looped head portion. The cross-section includes a convex outer periphery with two terminating ends disposed on opposite sides of the string web, a first axis perpendicular to the string web and passing through the terminating ends of the outer periphery, and an inner periphery opposite to the outer periphery and having two flat portions extending inwardly from a respective terminating end of the outer periphery and disposed along the first axis. The inner periphery further has an inner convex portion disposed between and interconnecting the flat portions. The cross-section has an axis of symmetry extending along the string web and perpendicular to the first axis. The axis of symmetry passes through a first point on the inner convex portion. The outer periphery has a central portion divided by the axis of symmetry at a second point. The central portion is indented to form a peripheral groove aligned with the inner convex portion. The second point is a point on the central portion before the central portion was indented. The distance of the first point from the first axis is shorter than that of the second point from the first axis.
