The Odyssey Ai-ONE Milled 8T is a full-milled mallet putter designed to combine classic milled-putter feel with modern tech that improves forgiveness and roll consistency. It offers a stable, mid-size mallet shape that aims to deliver consistent ball speed — even on off-centre strikes — making it a strong choice if you want a dependable putter from all parts of the face. 

Key Features

• Milled stainless-steel head + titanium “Ai-ONE” insert: The 8T’s head is fully milled for precision, and it uses Odyssey’s AI-designed titanium insert. The insert’s contoured backside is engineered to maintain more consistent ball speed across the face — so mishits lose less speed/distance than on many traditional milled putters. 

• Rounded high-MOI mallet profile: The 8T is the largest of Odyssey’s rounded mallet shapes — mixing stability and forgiveness with a head shape that’s easy to align and comfortable at address. 

• Slant-neck hosel (S version) — moderate toe hang (~36°): This gives the 8T a touch of toe-hang — useful if your stroke features a bit of arc or face rotation, while still being tame enough for controlled mallet feel without heavy toe-hang.

• Adjustable front-weighting system: Like other Ai-ONE Milled models, the 8T allows interchangeable sole weights (5, 10, 15, 20 g) so you can tune head weight and feel to match your putting stroke and green conditions. 

• Premium Aesthetic + Finish: The putter features a navy-blue PVD finish and a gold-toned titanium face insert — a high-end, tour-style look.

• SL 90 Stroke Lab Shaft with counter-balanced feel: The shaft is lighter but includes counter-balance weight in the grip end — which can help with stroke stability and smoother tempo through the stroke.
