two or more of the openings in the top surface are disposed within each of the first, second, and third recessed portions.
10. The golf putter head of claim 6 , wherein:
a plurality of inserts disposed at different locations along an inside top surface of the hollow body, the inserts include openings that define the different available locations along the top surface of the hollow body; and
the weights are configured to be inserted into the openings of the inserts.
11. The golf putter head of claim 6 , wherein:
the golf putter head includes a plurality of openings that define the different available locations, and a plurality of weight holders or sleeves configured to be slidably inserted into the corresponding openings; and
the weights are configured such that one or more of the weights are insertable into any one or more of the weight holders or sleeves for adjusting a center of gravity of the golf putter head in three dimensions.
12. A golf putter comprising the golf putter head of claim 6 , coupled to a shaft, wherein the golf putter head includes a material defining the hollow body portion, the bottom portion, and the interior cavity such that the golf putter head is configured to use spring force for putting a golf ball.
