Cobra built the Grandsport 35 around a 3D-printed lattice core, and the payoff is stability you notice on a mishit. It putts beautifully from long range. From the middle distances it is a different story.
What's new
The Grandsport 35 is a modern blade in Cobra's 2026 3DP Tour line. Its 304 stainless body carries carbon fiber, tungsten, and a 3D-printed nylon lattice cartridge that pushes mass to the perimeter, which Cobra says raises MOI. A traditional plumber's neck keeps it looking like a blade at address.
Cobra mills the face, a MIM-formed piece of 304 stainless, with Descending Loft Technology, four lofts that step down across its height. It comes with a KBS CT Tour 120 shaft and a SuperStroke grip, and adjustable heel and toe weights shift 5 to 10 grams. It sells at premium money, priced with the rest of the 3DP Tour line.
How it plays
Lag putting is its strength. In head-to-head testing it posted a -7.1 handicap on long putts and -5.6 on short ones, and on that scale a more negative number is better. Forgiveness and feel both score 8.5, the highest marks it earns.
The lattice core keeps the face steady on off-center hits, and the milled face gives a firm, solid strike. One review gave it 4.5 out of 5, and an earlier Grandsport won a Most Wanted Blade title in 2022, so the shape has a following. Workability scores 8.4, and the plumber's neck is built for an arcing stroke.
Where it lacks
Mid-range putts drag the whole result down. Its +3.3 handicap from the middle distances is the weakest of its three figures and pulls the overall test number to -3.7, a middling mark for a putter at this price.
Accuracy scores 7.5, its lowest rating, and distance control sits at 7.7. Anyone with a straight-back, straight-through stroke should also look elsewhere, because the plumber's neck is set up for an arc.
“On a long lag I trust it completely. From mid-range I want a little more help.”- The Club Stand gear team
Reasons to buy
- Strong lag putting in testing, with long putts its best distance by a clear margin
- Milled 304 stainless face feels solid, and one review scored the putter 4.5 out of 5
- Adjustable heel and toe weights let you fine-tune head weight by 5 to 10 grams
Reasons to think twice
- Mid-range putts tested poorly, well behind its short and long results
- Accuracy is its lowest score, so it trails its own feel and forgiveness numbers
- Priced at premium money, and the plumber's neck mostly suits players with an arcing stroke
