 a sole recess; and 
 a sole blind hole, wherein a major axis of the sole blind hole is substantially parallel to the striking face portion, and wherein the major axis of the sole blind hole runs along a substantially heel-to-toe direction; and 
   a removable weight assembly comprising:
 a cylindrical weight to fit into the sole blind hole in an installed position; and 
 a weight cover to cover the cylindrical weight in the installed position. 
   
     
     
         2 . The golf club head of  claim 1 , wherein the major axis is located at a distance between about 2.0 mm and about 12.0 mm from the striking face portion. 
     
     
         3 . The golf club head of  claim 1 , wherein the major axis is parallel to the striking face portion. 
     
     
         4 . The golf club head of  claim 1 , wherein an angle formed between the major axis and the striking face portion is between about −5 degrees and about 5 degrees. 
     
     
         5 . The golf club head of  claim 1 , wherein the weight cover further comprises:
 a cap to cover the cylindrical weight in the installed position, wherein the cap comprises a cap through hole; and   a fastening mechanism to secure the cylindrical weight in the installed position.   
     
     
         6 . The golf club head of  claim 5 , wherein the cap comprises a fastening recess to receive a portion of the fastening mechanism, and wherein the fastening mechanism comprises a weight recess to receive a portion of the cylindrical weight. 
     
     
         7 . The golf club head of  claim 5 , wherein in the installed position, a geometric center of the cylindrical weight and a geometric center of the cap through hole are aligned with the major axis. 
     
     
         8 . The golf club head of  claim 1 , wherein the cylindrical weight comprises a metal. 
     
     
         9 . The golf club head of  claim 8 , wherein the metal comprises one of tungsten, steel, and titanium. 
     
     
         10 . The golf club head of  claim 1 , wherein the sole comprises a first material. 
     
     
         11 . The golf club head of  claim 10 , wherein the weight cover comprises the first material. 
     
     
         12 . The golf club head of  claim 1 , wherein the weight cover is stainless steel. 
     
     
         13 . A golf club head, comprising:
 a striking face portion;   an upper back portion extending backward from at least a top portion of the striking face portion;   a sole extending backward from at least a bottom portion of the striking face portion, wherein the sole comprises a toeward sole portion, wherein the toeward sole portion comprises a sole blind hole, wherein a major axis of the sole blind hole is substantially parallel to the striking face portion, and wherein the major axis of the sole blind hole runs along a heel-to-toe direction; and   a cylindrical weight to fit into the sole blind hole in an installed position.   
     
     
         14 . The golf club head of  claim 13 , wherein a heelward portion of the sole blind hole comprises threads. 
     
     
         15 . The golf club head of  claim 14 , wherein a portion of the cylindrical weight comprises threads to engage the threads of the sole blind hole thereby securing the cylindrical weight to the golf club head. 
     
     
         16 . The golf club head of  claim 13 , wherein the cylindrical weight comprises a metal. 
     
     
         17 . The golf club head of  claim 16 , wherein the metal comprises one of tungsten, steel, and titanium. 
     
     
         18 . A golf club head, comprising:
 a striking face portion;   an upper back portion extending backward from at least a top portion of the striking face portion;   a sole extending backward from at least a bottom portion of the striking face portion, wherein the sole comprises:
 a toeward sole portion, wherein the toeward sole portion comprises a first sole recess; 
 a heelward sole portion, wherein the heelward sole portion comprises a second sole recess; and 
 a weight through hole, wherein a major axis of the weight through hole is substantially parallel to the striking face portion, and wherein the major axis of the weight through hole runs along a heel-to-toe direction; and 
   a removable weight assembly comprising:
 a cylindrical weight to fit into the weight through hole in an installed position; 
 a first weight cover to cover the first sole recess in the installed position, wherein the first weight cover comprises a cover through hole to receive the cylindrical weight; and 
 a second weight cover to cover the second sole recess in the installed position, wherein the second weight cover comprises a cover blind hole to receive a second portion of the cylindrical weight.
