When LAB Golf announced the new OZ.1 HS (Heel Shafted) putter, it wasn’t just another addition to the lineup. It represented years of engineering, refinement, and bold innovation in the pursuit of a torque-free heel-shafted putter—something that many golfers believed was nearly impossible. At the centre of this breakthrough is the innovative riser hosel design, carefully developed to maintain Lie Angle Balance while preserving the traditional look and feel heel-shafted players demand.
The Challenge of Heel-Shafted Torque
Golfers who prefer heel-shafted putters know the feel and flow they deliver, but they also come with a drawback: torque. With most heel-shafted models, face rotation is inevitable, demanding extra manipulation from the golfer. The LAB design team set out to answer a simple question: Could you create a heel-shafted putter that remains torque-free—just like the DF3 or Mezz.1—without compromising balance or aesthetics?
Rethinking the Hosel
The solution came in the form of an innovative riser hosel design. Unlike traditional hosels, which create offset but fail to balance torque, the OZ.1 HS hosel was engineered to interact directly with the head’s geometry. The riser shifts the shaft’s insertion point upward and outward, redistributing weight so the putter naturally wants to stay square to the target line.
This wasn’t achieved overnight. LAB Golf’s team went through countless prototypes, testing combinations of hosel height, shaft entry angle, and mass distribution before finding the formula that finally delivered a torque-free heel-shafted option.
The Science Behind the Innovation
-
Lie Angle Balance Integration: By positioning the shaft through the riser hosel, the OZ.1 HS maintains LAB’s patented torque-free stability, ensuring the face stays square without manipulation.
-
Visual Flow for Heel-Shaft Players: The hosel maintains the look and feel that traditional heel-shafted golfers prefer, blending innovation with familiarity.
-
Consistency Through Impact: Less torque means reduced face twist, translating into straighter rolls, tighter dispersion, and greater confidence on the greens.
A Putter for the Purist—Without the Compromise
For players who have always gravitated toward heel-shafted putters, the OZ.1 HS offers the best of both worlds: the flow and setup you know, with the performance of torque-free design. It’s not a redesign of the wheel—it’s a reinvention of how the wheel rolls.
Why the OZ.1 HS Matters for Golfers
With the launch of the LAB Golf OZ.1 HS, golfers now have access to a heel-shafted putter that doesn’t force them to choose between tradition and technology. By innovating at the hosel level, LAB has made it possible for players to enjoy a design that looks familiar at address while delivering the unmatched stability of Lie Angle Balance.
For golfers serious about improving their putting, this isn’t just a new model—it’s a new category of performance.
