Multi-material iron type golf club head

1. A method of forming an iron type golf club head comprising:

partially forging a blade portion and a heel muscle region of said iron type golf club head with a cavity near a bottom sole portion of said blade portion from a first material;

partially forging a hosel portion of said iron type golf club head from a second material;

joining said blade portion to said hosel portion to create a partially forged golf club head;

forging said partially forged golf club head into said iron type golf club head,

wherein said step of joining said blade portion to said hosel portion is accomplished via a threaded mechanism.

2. The method of claim 1 , wherein said second material has a Brinell HB hardness less than about 250.

3. The method of claim 2 , wherein said second material has a Brinell B hardness less than about 225.

4. The method of claim 3 , wherein said second material has a Brinell HB hardness less than about 200.

5. The method of claim 4 , wherein said second material has a Brinell HB hardness less than about 175.

6. The method of claim 5 , wherein said second material has a Brinell HB hardness less than about 150.

7. The method of claim 1 , wherein said blade first material has a yield strength of greater than about 570 MPa, and wherein said second material has a yield strength less than about 570 MPa.

8. The method of claim 7 , wherein said first material is 17-4 stainless steel and said second material is 304 stainless steel.

9. The method of claim 7 , wherein said first material is K301 steel and said second material is 1020 steel.

10. An iron type golf club head comprising:

a blade portion, made out of a first material, located near a terminal end of said iron type golf club head, said blade portion defining a striking face adapted for striking a golf ball and forming a cavity near a bottom sole portion of said blade portion;

a hosel portion, made out of a second material, located near a proximal end of said iron type golf club head; and

wherein said first material has a yield strength greater than about 570 MPa,

wherein said second material has a yield strength less than about 570 MPa, and

wherein said second material has a Brinell HB hardness less than about 250,

wherein said first material is 17-4 stainless steel and said second material is 304 stainless steel.

11. The iron type golf club head of claim 10 , wherein said second material has a Brinell HB hardness less than about 225.

12. The iron type golf club head of claim 11 , wherein said second material has a Brinell HB hardness less than about 200.

13. The iron type golf club head of claim 12 , wherein said second material has a Brinell HB hardness less than about 175.

14. The iron type golf club head of claim 13 , wherein said second material has a Brinell HB hardness less than about 150.

15. The iron type golf club head of claim 10 , wherein said blade portion and said hosel portion are joined together via a welding process.

16. An iron type golf club head comprising:

a blade portion including a heel muscle region, made out of a first material, located near a terminal end of said iron type golf club head, said blade portion defining a striking face adapted for striking a golf ball; and

a hosel portion, made out of a second material, located near a proximal end of said iron type golf club head;

wherein said blade portion including said heel muscle region is forged from a unitary piece of material, and

wherein said first material has an average Brinell HB hardness greater than 375,

wherein said first material is 17-4 stainless steel and said second material is 304 stainless steel.

17. The iron type golf club head of claim 16 , wherein said second material has an average Brinell HB Hardness less than 200.
