Quaternion – Mathematics meets motion. Stability meets feel.

The Quaternion is the most conceptual and technically advanced model in the iBPutter Sweet Spot collection.
Its name is inspired by quaternion mathematics — a complex number system used to describe three-dimensional rotation — perfectly aligned with the core idea of putting: a symmetrical, controlled motion in space without distortion or torque.
Built with a centered shaft, true bilateral symmetry, and a unique cylindrical head structure, the Quaternion delivers exceptional visual alignment and stroke balance.
It also features our anti-vibration shaft system, designed to absorb unwanted feedback and amplify the sensation of a clean, centered impact — allowing the player to focus purely on rhythm, control, and flow.
This is a putter for players who appreciate pure geometry, refined feedback, and a stroke that feels as balanced as it looks.
