Abstract
A set of golf club irons includes variably spaced hosel offsets for each club, with the hosel offset increasing from the higher numbered clubs to the lower numbered clubs. Each of the club heads is provided with a matching center of gravity, and the hosel is shifted toward the center of gravity for the higher numbered clubs and outwardly away from the center of gravity for the lower numbered clubs. This has the effect of reducing the moments of inertia for the higher numbered clubs, thereby providing less stability and greater control for those clubs, and increasing the moments of inertia for the lower numbered clubs, thereby providing greater stability while sacrificing some control. The effect is to provide greater consistency for the lower numbered clubs used for longer distance drives, while providing greater control for higher numbered clubs generally used for shorter shots approaching the green, where accuracy is more important. Optionally, a medial club (e.g., the six iron) may be selected as an intermediate datum for the hosel offset, with the offset decreasing toward the higher numbered clubs and increasing toward the lower numbered clubs.
