Abstract: A set of iron-type golf clubs and a set of iron-type golf club heads are disclosed. The loft angles of the heads are gradually increased from the lowest numbered golf club to the highest numbered golf club in the set. Given that a coefficient of inertia of the head is the ratio Ms/M of a moment of inertia Ms (gram sq·cm) of the head around a horizontal axis extending in a toe-heel direction of the head passing through the center of gravity of the head, to the mass M (g) of the head, the coefficient of inertia is gradually increased with the increase in the loft angle, and the difference of the coefficient of inertia of the head of the highest numbered club from that of the lowest numbered club is 0.3 or more.

Abstract: A golf club head includes a top portion, a sole portion opposite the top portion, and a striking face configured to impact a golf ball. The striking face includes a face center and a variable thickness distribution such that the club head exhibits an Expected COR value of not less than 0.810, the Expected COR value being determined based on the following relationship: Expected   COR = ∑ i = 1 n  ∑ j = 1 m  p ij * c ij The variable cij corresponds to an average COR value associated with bin i, j, and the variable pij corresponds to a bin-specific impact probability value. And the club head exhibits a characteristic time no greater than 257 microseconds.
