An iron-type golf clubhead includes a blade, a hosel, and a junction. The blade includes a rearwardly facing blade cavity, and the junction includes a rearwardly facing junction cavity that is coextensive with the blade cavity. A graduated weight pad is located within the blade cavity and preferably has a height, in a direction perpendicular to the blade face, that varies in a toe-to-heel direction, and which may also vary from the top to the bottom of the club. The junction cavity may also include a negative weight cutout that extends below the junction cavity floor and that represents a continuation of the profile of the weight pad, in effect forming a negative weight pad. The junction cavity and weight pad act to move the center of gravity outwardly toward the toe, and also to increase the sweet spot on the outer, toe portion of the clubhead.

La présente invention vise une tête de bâton de golf comprenant une lame, une douille et une pièce de jonction. La lame et la pièce de jonction comportent un creux sur leur face arrière, se prolongeant l'un dans l'autre. Un poids gradué est inséré dans la cavité ménagée dans la lame; de préférence, la hauteur de ce dernier, c'est-à-dire la dimension perpendiculaire à la face de la lame, diminue dans le sens pointe-talon, et peut également varier dans le sens vertical. La cavité de la pièce de jonction peut aussi comporter un espace se prolongeant sous le fond de la cavité et destiné à recevoir un poids négatif. Le poids placé dans la cavité de la pièce de jonction permet de déplacer le centre de gravité vers l'extérieur, du côté de la pointe du bâton, et d'augmenter le point d'impact à cet endroit.
