Abstract

This invention provides an iron golf club head comprising a face surface with a plurality of scorelines formed in it, and an indicating portion which indicates at least the cross-sectional shape of the scoreline.

What is claimed is: 
     
         1 . An iron golf club head comprising:
 a face surface with a plurality of scorelines formed therein; and   an indicating portion which indicates at least a cross-sectional shape of the scoreline.   
     
     
         2 . The head according to  claim 1 , wherein
 said indicating portion is provided with a groove which indicates the scoreline, and   said indicating portion includes   a first surface indicating a shape of said groove as viewed from a front, and   a second surface which is perpendicular to said first surface, and a direction in which said groove extends, and indicates a cross-sectional shape of said groove as the cross-sectional shape of the scoreline.   
     
     
         3 . The head according to  claim 1 , wherein said indicating portion is disposed in a portion, that cannot be seen as the golf club head is viewed from a top, when the face surface is set on a horizontal plane at a specific lie angle while the face surface is matched with a flight trajectory direction. 
     
     
         4 . The head according to  claim 3 , wherein
 the golf club head includes a back portion which forms a back surface thereof, and   said indicating portion is disposed in said back portion.

         6 . The head according to  claim 1 , wherein said indicating portion indicates a cross-sectional shape larger than the cross-sectional shape of the scoreline by a factor of 1 (inclusive) to 3 (inclusive). 
     
     
         7 . The head according to  claim 1 , further comprising:
 an indicating member including said indicating portion; and   a main body portion provided with a recess which receives said indicating member.
