More specifically, the present invention relates to a golf club head wherein the striking face portion has two regions of increased thickness to improve the performance of the golf club head. ## Claims ### Claim 1 An iron type golf club head comprising: a striking face portion located at a frontal portion of said iron type golf club head, adapted to strike a golf ball; wherein said striking face portion has an external frontal surface that is substantially planar, wherein said striking face portion has an internal rear surface that is uneven, wherein said external frontal surface and said internal rear surface combine to define a thickness of said striking face portion, and wherein said striking face portion further comprises; a first region of increased thickness, located near a centroid of said striking face portion, and a second region of increased thickness, located away from said centroid of said striking face portion, a body portion attached to a rear of said iron type golf club head, wherein said second region of increased thickness is located at a distance of between about 8.0 mm to about 9.0 mm heelward from said first region of increased thickness, and wherein said second region of increased thickness is located at a distance of between about 7.0 mm to about 10.0 mm lower on said striking face portion from said first region of increased thickness. ### Claim 2 (depends on 1) The iron type golf club head of claim 1, wherein said second region of increased thickness is located at a distance of between about 8.25 mm to about 8.75 mm heelward from said first region of increased thickness, and wherein said second region of increased thickness is located at a distance of between about 8.0 mm to about 9.0 mm lower on said striking face portion from said first region of increased thickness. ### Claim 3 (depends on 2) The iron type golf club head of claim 2, wherein said second region of increased thickness is located at a distance of about 8.75 mm heelward from said first region of increased thickness, and wherein said second region of increased thickness is located at a distance of about 8.5 mm lower on said striking face portion from said first region of increased thickness. ### Claim 4 (depends on 1) The iron type golf club head of claim 1, wherein a first thickness of said first region of increased thickness is thicker than a second thickness said second region of increased thickness. ### Claim 5 (depends on 4) The iron type golf club head of claim 4, where said first thickness is more than about 1.10 times greater than said second thickness. ### Claim 6 (depends on 5) The iron type golf club head of claim 5, wherein said first thickness is more than about 1.12 times greater than said second thickness. ### Claim 7 (depends on 6) The iron type golf club head of claim 6, wherein said first thickness is more than about 1.13 times greater than said second thickness. ### Claim 8 (depends on 7) The iron type golf club head of claim 7, wherein said first thickness is between about 2.00 mm to about 2.20 mm. ### Claim 9 (depends on 8) The iron type golf club head of claim 8, wherein said first thickness is between about 2.05 mm to about 2.15 mm. ### Claim 10 (depends on 9) The iron type golf club head of claim 9, wherein said first thickness is about 2.10 mm. ### Claim 11 An iron type golf club head comprising: a striking face portion located at a frontal portion of said iron type golf club head, adapted to strike a golf ball; wherein said striking face portion has an external frontal surface that is substantially planar, wherein said striking face portion has an internal rear surface that is uneven, wherein said external frontal surface and said internal rear surface combine to define a thickness of said striking face portion, and wherein said striking face portion further comprises; a second region of increased thickness, located at a location that is 15 mm upwards from a ground plane, and at a distance that is a midpoint of a full length scoreline, a first region of increased thickness, located toeward of said second region of increased thickness, a body portion attached to a rear of said iron type golf club head. ### Claim 12 (depends on 11) The iron type golf club head of claim 11, wherein said first region of increased thickness is located higher up on said striking face portion than said second region of increased thickness. ### Claim 13 (depends on 12) The iron type golf club head of claim 12, wherein a first thickness of said first region of increased thickness is thicker than a second thickness said second region of increased thickness. ### Claim 14 (depends on 13) The iron type golf club head of claim 13, where said first thickness is more than about 1.10 times greater than said second thickness. ### Claim 15 (depends on 14) The iron type golf club head of claim 14, wherein said first thickness is more than about 1.12 times greater than said second thickness. ### Claim 16 (depends on 15) The iron type golf club head of claim 15, wherein said first thickness is between about 2.00 mm to about 2.20 mm. ### Claim 17 An iron type golf club head comprising: a striking face portion located at a frontal portion of said iron type golf club head, adapted to strike a golf ball; wherein said striking face portion has an external frontal surface that is substantially planar, wherein said striking face portion has an internal rear surface that is uneven, wherein said external frontal surface and said internal rear surface combine to define a thickness of said striking face portion, and wherein said striking face portion further comprises; a second region of increased thickness, located at a location that is 15 mm upwards from a ground plane, and at a distance that is a midpoint of a full length scoreline, a first region of increased thickness, located near a centroid of said striking face portion a body portion attached to a rear of said iron type golf club head, and wherein a first thickness of said first region of increased thickness is thicker than a second thickness said second region of increased thickness.
