         4 . The golf club head of  claim 1 , wherein a width of the removable weight is more than about 80% of a width of the back flange. 
     
     
         5 . The golf club head of  claim 1 , wherein a width of the body portion is less than a width of the cover portion. 
     
     
         6 . The golf club head of  claim 1 , wherein a width of the body portion is about 25% of a width of the cover portion. 
     
     
         7 . The golf club head of  claim 1 , wherein a height of the body portion is larger than a height of the cover portion. 
     
     
         8 . The golf club head of  claim 6 , wherein a depth of the body portion is less than a depth of the cover portion. 
     
     
         9 . The golf club head of  claim 1 , wherein the fastener comprises a fastener axis running along a heel-to-toe direction. 
     
     
         10 . A golf club head, comprising:
 a striking face portion;   a back portion comprise:
 an upper blade portion; 
 a gutter extending downward from the upper blade portion; and 
 a lower muscle portion extending downward from the gutter, wherein the lower muscle portion comprises:
 a back flange, wherein the back flange comprises:
 a weight recess extending into a sole; and 
 a fastener through hole accessible to the weight recess; and 
 
 the sole extending backward from a lower portion of the striking face portion to the back flange; 
 
   a removable weight to fit into the weight recess, comprising:
 a weight through hole accessible to the fastener through hole; 
 a body portion covered by the sole in an installed position, wherein the body portion fits into a portion of the weight recess; and 
 a cover portion to cover the weight recess in the installed position; and 
   a fastener to secure the removable weight in the installed position via the fastener through hole.   
     
     
         11 . The golf club head of  claim 10 , wherein the removable weight comprises a metal. 
     
     
         12 . The golf club head of  claim 10 , wherein the metal comprises one of tungsten, steel, titanium, aluminum, scandium, zinc, nickel, copper, and iron. 
     
     
         13 . The golf club head of  claim 10 , wherein a width of the removable weight is more than about 80% of a width of the back flange. 
     
     
         14 . The golf club head of  claim 10 , wherein a width of the body portion is less than a width of the cover portion. 
     
     
         15 . The golf club head of  claim 10 , wherein the fastener comprises a fastener axis, and wherein the fastener axis is perpendicular to an exterior surface of the back flange. 
     
     
         16 . The golf club head of  claim 10 , wherein a first portion of the removable weight extends partially faceward in the installed position, and wherein a second portion of the removable weight extends partially backward in the installed position. 
     
     
         17 . A golf club head, comprising:
 a striking face portion;   a back portion comprise:
 an upper blade portion; 
 a gutter extending downward from the upper blade portion; and 
 a lower muscle portion extending downward from the gutter, wherein the lower muscle portion comprises:
 a back flange, wherein the back flange comprises a weight recess; and 
 a sole extending backward from a lower portion of the striking face portion to the back flange, wherein the sole comprises a toeward sole portion, wherein the toeward sole portion comprises a fastener through hole accessible to the weight recess, 
 
   a removable weight to fit into the weight recess, comprising:
