Abstract
An all metallic club head including a hollow body and a sole plate attached in a cut-out in the hollow body. The hollow body includes a front wall providing a generally flat impact face of a club head, a top wall defining a generally round upper side of the club head, a rear wall defining a back of the club head and a bottom wall providing the cut-out through which the hollow body opens downwards and a hosel extending integrally from the top wall. The front wall has a lower half which increases its thickness towards the edge of the cut-out. The sole plate is provided on its inner side with a raise extending longitudinally adjacent to the lower end of the front wall to form a weighting block on the heel side and a further weighting block on the toe side of the club head. The toe side weighting block is heavier than the heel side weighting block.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
