Golf club with visual feature indicator

1. A method of constructing a golf club head for improved visual feature recognition, the method comprising:

providing a golf club head having a bore adapted to receive a golf club shaft, wherein the bore extends through the golf club head between a hosel end and a sole, and wherein the golf club head has a plurality of design attributes;

selecting a polymeric plug having a color that corresponds to at least one of the plurality of design attributes;

inserting the polymeric plug into the bore from the hosel end such that a portion of the plug extends proud of the sole;

removing the proud portion of the plug by cutting or grinding;

polishing a portion of the polymeric plug that is flush with the sole using a solvent or head treatment; and

wherein the polished portion of the polymeric plug is outwardly visible to provide an indication of the at least one of the plurality of design attributes.

2. The method of claim 1 , further comprising restraining the polymeric plug from passing entirely through the bore by slidably contacting a feature of the polymeric plug and a corresponding restraining feature of the bore.

3. The method of claim 2 , wherein the restraining feature of the bore includes a ledge, a chamfer, or a bevel disposed between a portion of the bore having a first diameter and a portion of the bore having a second diameter.

4. The method of claim 3 , further comprising adhering a golf club shaft within the bore, wherein the golf club shaft prevents removal of the polymeric plug through the hosel end of the bore.

5. The method of claim 1 , wherein the at least one of the plurality of design attributes includes a loft angle, a sole profile, a metal type, mass distribution profile, or a face milling pattern.

6. The method of claim 1 , wherein the polymeric plug is formed from an acrylic material, and wherein the solvent includes acetone; and

wherein polishing the portion of the polymeric plug using the solvent causes the portion of the polymeric plug to have a smoother surface finish.

7. A golf club having improved visual feature recognition, the golf club comprising:

a golf club head coupled to a golf club shaft, wherein the golf club head includes:

a hosel defining a bore, wherein the bore has a first portion having a first diameter, a second portion having a second diameter that is smaller than the first diameter, and a transition from the first diameter to the second diameter;

a sole; and

a design attribute;

wherein the golf club shaft is disposed within the first portion of the bore and secured to the hosel, and wherein the bore extends through the golf club head to the sole;

a polymeric plug disposed within the bore between the golf club shaft and the sole, wherein the polymeric plug includes a restraining feature that contacts the transition to prevent withdrawal of the polymeric plug through the sole; and

wherein the polymeric plug is a color that corresponds to the design attribute.

8. The golf club of claim 7 , wherein a portion of the polymeric plug is disposed within the second portion of the bore; wherein the portion of the polymeric plug has a diameter that is smaller than the second diameter to accommodate an adhesive layer between the polymeric plug and the second portion of the bore; and

wherein the golf club further comprises an adhesive disposed between the portion of the polymeric plug and the second portion of the bore.

9. The golf club of claim 7 , wherein the transition includes a ledge, a chamfer, or a bevel.

10. The golf club of claim 7 , wherein the design attribute is a loft angle, a sole profile, a metal type, mass distribution profile, or a face milling pattern.

11. The golf club of claim 7 , wherein the polymeric plug is formed from an acrylic material.

12. The golf club of claim 7 , wherein the golf club head is a wedge having a loft angle of from about 48 degrees to about 64 degrees; and

wherein the design attribute is a sole profile.

13. The golf club of claim 7 , wherein the second bore has a volume of from about 800 mm 3 to about 1200 mm 3 .

14. The golf club of claim 7 , wherein the polymeric plug has an exposed surface area that is flush with the sole, and wherein the polymeric plug has a cross-sectional area that is transverse to a central longitudinal axis of the plug; and

wherein the exposed surface area is at least twice the size of the cross-sectional area to provide improved visual feature recognition.

15. The golf club of claim 7 , wherein the exposed surface area is greater than 80 mm 2 .
