Tri-Plane Sole Mallets

The Bobby Grace Tri-Plane Sole Mallet Putter is built around its sole, which bobbygraceputters.com describes as a patented Tri-Plane Sole. According to that same source, the design ensures the putter sits perfectly square and level at address, reduces twisting through impact and promotes consistent early roll. The site also credits the sole with creating less drag due to minimum contact with green surface, effective from fringe or off the green, and with allowing the player to putt at various lie angles with no need to adjust the shaft.

Bobbygraceputters.com attaches a specific tour anecdote to this putter, reporting a PGA Tour event in which a weekend finish of 66-64 needed only 51 putts, and crediting the putter with a wire-to-wire Major win the following week. That figure and the win it's tied to come from the maker's own site rather than from any independent verification, so the number is worth reading as marketing testimony rather than an established record.

Within the Tri-Plane Sole Mallets line, this release is defined almost entirely by its sole geometry rather than by head shape or face milling, at least as far as what's held here. The claims on file describe function, benefit, and a single dramatic result, which gives the reader a clear sense of how the putter was pitched, even without a broader spec sheet to set it against the rest of the line.
