BB41

The BB41 traces back to 2000, the Millennium Series entry that established the model's identity as a heel-toe-weighted blade. The maker's page lists a 303 Stainless Steel construction with weighted brass plugs set into the face and brass ingots positioned at the flange, heel, and toe, a weighting scheme that gave the original its particular balance and feel.

The line resurfaces decades later as a recurring vehicle for Bettinardi's Studio B Reserve and 25th Anniversary programs, always returning to that same classic blade shape. The maker's page for one 25th Anniversary run describes a 360 gram BB41F with a copper insert on a Flymill face and a one piece milled flow neck, and notes that the sole design pays tribute to the original Millennium Series putter, carrying forward the original Milled by Bettinardi engraving alongside a numbered engraving marking its limited run.

Later Studio B Reserve editions kept the BB41 name attached to variations built around the Flymill face. The Ancient Greece release, per the maker's page, is described as a classic heel-toe-weighted BB41F with a Mother of Pearl topline inlay and a Distressed Slate finish, an Aggressive Flymill face offering a moderate feel, and a Flow neck producing half toe hang suited to golfers with a moderate to maximum arc. The Galaxy edition, also per the maker's page, is built in 303 Stainless Steel with a Nebular finish running from neck to sole, a Flymill face for a moderate feel, a flange sightline, and three quarter toe hang aimed at golfers with maximum arc in their stroke.

Across these releases the BB41 line reads less as a single fixed design than as a name Bettinardi keeps returning to for limited and commemorative work, each time dressed in a different finish and neck configuration but anchored to the same heel-toe-weighted blade the maker's own pages trace back to that first Millennium Series putter.
