Abstract
Golf club-heads are disclosed that have a body and a face plate. Exemplary club-heads are hollow metal-wood club-heads. The face plate is attached to the front of the body and has obverse and reverse surfaces, and a peripheral zone, toe zone, heel zone, upper zone, lower zone, and central zone. The reverse surface defines in the central zone a recess surrounded by a substantially annular ridge. The reverse surface also defines in the toe zone and heel zone respective horizontal flanking recesses. The reverse surface also defines in the upper zone and lower zone respective vertical flanking recesses. The maximal thickness of the annular ridge is greater than the respective thicknesses of the central recess and flanking recesses, and the respective thicknesses of the flanking recesses are no greater than the thickness of the central recess.
