Golf club heads, both woods (11) and irons (30), have recessed areas (17) in the striking faces (19) of the club heads with an insert (49) secured therein. The insert (49) is of a laminated structure having multiple layers and so constructed that the outer layer (61) is of a substantially high strength to weight material and the center layers (65) are of a relatively lower weight material. This structure allows the insert (49) to be reduced in weight so as to allow the weight difference to be repositioned about the perimeter of the club head to achieve optimum weight distribution. One of the outer layers (61, 63) is preferably perforated to permit visual inspection of the center layer (65).

L'invention concerne des têtes de clubs de golf, aussi bien bois (11) que fers (30), qui présentent au niveau de leur face de frappe (19) une zone évidée (17) dans laquelle est fixée une pièce d'insertion (49). La pièce d'insertion (49) a une structure laminée formée de plusieurs couches, d'une manière telle que la couche externe (61) est constituée d'un matériau lourd très résistant et les couches centrales (65) d'un matériau relativement plus léger. Cette structure permet de diminuer le poids de la pièce d'insertion (49) et donc de repositionner la différence de poids autour du périmètre de la tête afin de répartir le poids d'une manière optimale. L'une des couches externes (61, 63) est de préférence perforée, ce qui permet l'inspection visuelle de la couche centrale (65).
