iBPUTTER Sweet Spot · Official Putter
A different way to think about the putter
Four distinctive models, one precision-first design philosophy and a return to the International Pairs World Final—meet the iBPUTTER Sweet Spot range heading to Tenerife.
Putting is often described as the simplest part of golf: one ball, one target and one controlled stroke. It is also where small differences in alignment, face control and contact can decide a round.
That tension sits at the centre of iBPUTTER Sweet Spot. The Spanish putter brand returns to the International Pairs stage as the Official Putter of the 2026 World Final, taking place in Tenerife from 5–9 October 2026. Its range does not try to hide every imperfect strike. Instead, the company’s stated philosophy is to make the centre of the face, balance of the head and quality of contact easier for the player to understand.
Balance the head. Clarify the strike.
Across all four models, iBPUTTER uses a centred shaft and a symmetrical, dual-face head. The brand describes the geometry as “Zero Torque”: the centre of gravity is aligned with the shaft axis so the head is designed to resist twisting through the stroke.
The other defining idea is the sweet spot itself. Instead of presenting a wide area of the face as equally forgiving, iBPUTTER concentrates attention on one central point of contact. A centred strike is rewarded; an off-centre strike gives the player direct feedback. It is a training-minded approach as much as a piece of equipment design.
Four models. Four ways into the same idea.
The current collection shares the same centre-shaft, symmetrical DNA, but changes the visual language, head weight and feel. That gives golfers a choice between the original cylindrical concept, more weight, a familiar blade-style profile or the most technical expression of the range.
373G · The Original
The design that established the iBPUTTER identity. Its 373-gram CNC-milled stainless-steel head combines a cylindrical alignment zone with a centred steel shaft and a deliberately precise feel.

410G · Precision With Presence
The 410G develops the original shape with a heavier 410-gram head. iBPUTTER positions that extra mass for golfers who prefer a more deliberate pendulum rhythm and a firmer sense of stability.

BX2 · Evolution in Balance
The BX2 keeps the centre-shaft and zero-torque concept but places it in a more conventional, compact silhouette. A 303 stainless-steel body and 6061 aluminium faces create a 380-gram head with familiar sightlines.

Quaternion · Geometry in Motion
The most concept-led model in the range uses bilateral symmetry, a cylindrical head structure and a steel-and-carbon anti-vibration shaft. Its name references quaternion mathematics, used to describe rotation in three dimensions.

A young brand with a clear point of view
iBPUTTER Sweet Spot was introduced in October 2023 at the Old Course at St Andrews. The 373G established the original formula; the 410G added mass, the BX2 translated the concept into a more conventional outline, and Quaternion took the geometry in a more technical direction.
That progression matters because the four models are not simply different finishes of the same head. Each one offers a distinct address picture and weight profile while retaining the defining centred-shaft, symmetrical construction.
The shape changes. The central idea stays the same.
Back on the World Final stage
iBPUTTER first joined the International Pairs World Final as Official Putter for Sun City in 2025. The partnership now continues in Tenerife, connecting a Spanish equipment brand with an international field of amateur golfers competing on the Canary Islands.
For International Pairs, the fit is easy to understand. A pairs championship is built on shared decisions, composure and execution under pressure. On the green, all of that narrows to a single line and a single strike.
