Innovation: Packing the MOI of a huge mallet into the size of blade

Round 4 is pioneering the development of 3D printed putters.  This new technology allows the creation of shapes and internal geometries that no other production technique can.


This design freedom, combined with our multi-material design approach, allows us to radically strip weight out of the areas of a putter where you don’t want it, and strategically add weight to the areas where you do.  Our new 3DP Design line achieves previously unimaginable MOI and forgiveness in traditionally shaped and sized blade putters.
