LAB Golf OZ.1i HS Putter (NEW Heel-Shafted Mallet Reviewed)

The unique LAB Golf OZ.1i HS putter is a new addition for 2025 as the first heel-shafted mallet to be launched by the brand.

The new HS model is the heel-shafted version of the popular LAB Golf OZ.1, and boasts the same familiar look of a classic mallet but with the twist of a heel-shafted hosel.

It makes it a first foray into this design by LAB Golf, who have previously focused only on center-shafted putters that have zero torque for maximum forgiveness.

The LAB Golf OZ.1i HS putter has all the same performance benefits and design elements, just with a heel-shafted hosel that appeals to a wider range of golfers.

Pros & Cons

✅ Traditional heel-shafted look appeals to golfers who want a familiar mallet design

✅ Enhanced visual alignment at address, thanks to the on-set design and heel-shaft placement
✅ 303 stainless steel face insert promotes a “hotter” feel off the face
✅ Excellent customization options
❌ Shaft lean and press grip take time to adjust to
❌ Sound and feel are distinctly firmer than LAB’s all-aluminum models
❌ Premium price point as with all LAB putters

LAB Golf OZ.1i HS Putter Design & Features

The OZ.1i HS is LAB’s first heel-shafted mallet and provides a more traditional look compared to the center-shafted models that have been the hallmark of the company.

Appealing to golfers who want the LAB performance levels but with a traditional putter appearance and setup, the heel-shafted model opens up the brand to a whole new audience.

The HS design offers a no-compromise blend of traditional heel-shafted mallet aesthetics with LAB’s automatic, torque-free performance.

LAB’s Lie Angle Balance Technology keeps the face square to the stroke path, regardless of arc or straight-back stroke, and results in a true roll and fewer pushed or pulled putts.

Unlike the soft feel of the one-piece aluminum construction of the OZ.1, the heel-shafted OZ.1i features a fly-milled 303 stainless steel face insert for a more firmer feel off the putter face and generates more rollout.

The OZ.1i is the first LAB model to allow a zero-degree vertical shaft lean (or the two-degree forward press lean), with this a more traditional design feature and allows any grip be used like other premium mallets.

LAB Golf OZ.1i HS Putter Review: Is It Any Good?

Like all LAB Golf putters, the OZ.1i HS excels at keeping the putter face square and stable, helping putts start on line and promoting a more repeatable stroke.

The mallet has very high forgiveness levels, excellent consistency and easy alignment from distance or short, nervy, must-make putts.

And as the first heel-shafted model, it gives a whole new audience of golfers the option of adding a LAB putter to the back with many having previously been put off by center-shaft setups.

The new insert provides a firmer feel and it is a recommended option for golfers who like more initial roll or who have found softer putters leave putts short.
