A golf club comprising:
a clubhead having a striking face, a toe portion, a heel portion, and a male hosel extending from the heel portion, the hosel including an attaching portion and an annular shoulder which extends outwardly from the attaching portion,
a tubular ferrule having first and second ends and an internal bore extending through the ferrule and provided by an internal surface, the internal surface having:
a first portion adjacent the first end providing a first portion of the bore which is sized to fit over the attaching portion of the hosel;
