High MOI Triangular Mallet

The High MOI Triangular Mallet is Bobby Grace's take on a high moment of inertia design built into a triangular mallet head, a shape choice that stands apart from the blade and toe-hang work more commonly associated with putters of this era. bobbygraceputters.com dates the design to 2000, though that figure comes from the maker's own site rather than any independent verification.

What the record holds beyond the shape is tour usage. bobbygraceputters.com credits the putter with tour victories for Retief Goosen, Vijay Singh, Bart Bryant, Fred Funk, and Greg Chalmers, a list that spans multiple major-caliber players rather than a single signature user. That same source describes the design as having been enthusiastically embraced and having won many tour victories for number one players, language worth noting as the maker's own characterization rather than an outside outlet's independent finding.

Within the broader Bobby Grace catalog, the High MOI Triangular Mallet reads as a design built around stability and a distinct silhouette, with its reputation resting largely on the tour résumé attributed to it by the maker rather than on independent editorial testing found in this record.
