3. The golf club head of claim 2 further comprising at least two narrow projections positioned behind the control means in a front to rear direction and extending outwardly from the sole.

4. The golf club head of claim 3 wherein the projections are positioned adjacent the trailing edge of the club head.

5. The golf club head of claim 1 wherein the control means includes a plurality of cavities formed in the sole.

6. The golf club head of claim 5 wherein the plurality of cavities are arranged parallel to each other.

7. The golf club head of claim 5 wherein the cavities include flared ends at the heel and toe.

8. The golf club head of claim 5 wherein the cavities extend from adjacent the heel to adjacent the toe.

9. The golf club head of claim 5 wherein the cavities are angled diagonally with respect to the leading and trailing edges.

10. The golf club head of claim 5 wherein the cavities are arranged in a cross-hatched configuration on the sole.

11. The golf club head of claim 5 wherein the plurality of cavities form an array between the heel and the toe.

12. The golf club head of claim 5 wherein the plurality of cavities are formed in rows and each of the rows is parallel to the other.

13. The golf club head of claim 11 wherein the plurality of cavities are half-mooned shaped.

14. The golf club head of claim 11 wherein the plurality of cavities are oval shaped.

15. The golf club head of claim 11 wherein the plurality of cavities are straight.

16. The golf club head of claim 11 wherein the plurality of cavities are curved.

17. The golf club head of claim 5 wherein the plurality of cavities are curved toward the leading edge.

18. The golf club head of claim 5 wherein the plurality of cavities are curved toward the trailing edge.

19. The golf club head of claim 1 wherein the control means are projections extending between the heel and the toe.

20. The golf club head of claim 19 wherein the projections are triangular shaped members.

21. The golf club head of claim 19 wherein the projections are arranged in a cross-hatched configuration on the sole.

22. The golf club head of claim 1 wherein the control means includes a pair of projections extending outwardly from the sole.

23. The golf club head of claim 19 wherein the projections are raised members having a height of at least 1/16 of an inch from the sole.

24. The golf club head of claim 19 wherein the projections have a width in a front to rear direction of at least 1/8 of an inch.

25. An iron-type golf club head for hitting a golf ball comprising:

golf club head body having a heel, toe, top ridge, sole, rear club face having a trailing edge at the intersection of the sole and the rear club face, and a lofted ball striking face having a loft of at least 12°

with a forwardmost progression forming a leading edge at the intersection of the sole and the ball striking face;

control means integrally formed in the sole of the club head for contacting ground surfaces and providing greater control and stability during the execution of the golf shot and being spaced behind the leading edge of the club head, the control means extending between the heel and the toe, the control means including one or more cavities having a wall facing the leading edge of the club head.

26. The golf club head of claim 25 wherein the control means includes a plurality of the cavities.

27. The golf club head of claim 26 wherein the cavities are spaced so that the walls of the cavities cooperate to provide a substantially continuous wall in the heel to toe direction.

28. The golf club head of claim 26 wherein the club head includes at least two rows of cavities extending in a heel to toe direction.

29. The golf club head of claim 25 wherein the control means extends at least 35% of the distance between the heel and the toe.

30. The golf club head of claim 25 wherein the control means extends at least 50% of the distance between the heel and the toe.

31. The golf club head of claim 25 wherein the control means extends at least 70% of the distance between the heel and the toe.

32. An iron-type golf club head for hitting a golf ball comprising:

golf club head body having a heel, toe, top ridge, sole, rear club face having a trailing edge at the intersection of the sole and the rear ciub face, and a lofted ball striking face having a loft of at least 12°

with a forwardmost progression forming a leading edge at the intersection of the sole and the ball striking face;

control means integrally formed to the sole of the club head for contacting ground surfaces and providing greater control and stability during the execution of the golf shot and being spaced behind the leading edge of the club head, the control means extending between the heel and the toe, the control means including one or more projections having a frontal wall facing the leading edge of the club head.

33. The golf club head of claim 32 wherein the control means includes a plurality of the projections.
