Abstract
A putter-head () has its center of mass () spaced p mm behind its impact-face () at a height hmm above the head-bottom (), a loft angle αat height 12 mm above the head-bottom (), a moment of inertia/kg-mmabout the vertical axis through the center of mass (), a mass M kg and a radius of gyration of K mm about the heel-toe axis () of the head through the center of mass (), where p/l is not more than 0.18, his less than [12−p×sin(α)], and a parameter G=[p+(3.2+70×M)×K/p] is less than 350. The ratio d/K is less than 1.0, dmm being the vertical offset above the heel-toe axis () of the axis of attachment of the putter-shaft () to the putter-head (); the attachment-axis of the shaft may be spaced by no more than the shaft-radius from the center of mass. The impact-face () may have an upper flat section () that merges smoothly into a cylindrical lower section (), and the head () may be constructed with a high-density part () that extend lengthwise of the heel-toe axis and is either bonded to the underside of a lower-density part (), or forms both an upstanding front flange () and a rear body-section () of larger mass than, and spaced from, the flange ().
