In a first embodiment (fig. 2), a golf club head comprises a substantially convex striking face 34, preferably having a radius of around 19 millimetres. The lower surface of the club head may be substantially normal to the axis of the shaft 20, and the club head may have a rearward face 44 having a spoiling member 46 which prevents face 44 from being used as a playable striking face. A set of such clubs may be provided, each having a different convex profile. In a second embodiment (fig. 3), the club head comprises two striking faces 32, 34 having different orientations. The first face 32 may be substantially parallel to the axis of shaft 20, with the second face 34 being convex, angled (134, fig. 6) or concave (234, fig. 7). Second striking face 34 may comprise the upper surface of a protrusion 38 which protrudes from a lower part of first striking face 32, with the lower surface 40 of the protrusion being substantially normal to the axis of shaft 20. The club head of either embodiment may be formed from lightweight material. |
