Abstract
An improvement in iron golf clubs in which an unusually short, hollow hosel is provided thereby reducing weight of hosel and bridge that can be redistributed to the blade to increase the momentum that can be imparted to a golf ball. The hosel is disposed at the heel end of the blade lapping the heel end from the upper edge of the heel end downwardly, there being no bridge between the blade and the hosel below the hosel, the hosel extending from a level above the top of the blade down to the sole, the hosel having a through bore of constant diameter extending from the top of the hosel down through the sole. The lower end of the hosel, in developmental view of the sole taken from below, extending at an obtuse angle forwardly from the heel end of the blade in the manner of a dog-leg. A shaft fixedly secured in the bore and extending completely to the sole. In a modified construction, the sole end of the hosel is squared with the longitudinal axis of the hosel forming a step in the sole below the hosel reducing weight of metal that also can be redistributed to the blade.
