KING 3D Printed Grandsport Armlock Putter
The KING Grandsport Armlock putter is designed in a 41” setup with a special armlock-specific grip to promote the most consistent stroke for players that prefer to rest the grip and shaft against their lead forearm. A multi-material construction with SIK Face Technology creates the highest MOI possible for improved stability and roll accuracy.
Headcover included.
The Future
Starts Now.
We partnered with HP to design the first family of 3D printed multi-material putters to take MOI and stability to the next level.
The KING Grandsport-35 Armlock putter features an oversize blade shape, and a multi-material construction using a 3D printed nylon lattice, forged aluminum, tungsten, and SIK Face Technology to create our most forgiving and accurate blade style putter.

Grandsport-35 Tech
An intricate 3D printed nylon lattice cartridge optimizes the weight distribution within the putter head to create the highest MOI possible in a blade shape for more consistent and predictable rolls.

A 286g steel chassis lowers the center of gravity and adds structural stability to support the other components.

A lightweight 21g forged aluminum crown frees up discretionary weight to position more mass around the perimeter to increase MOI.

30 grams worth of tungsten weighting is combined in the heel and toe to maximize stability on off-center putts for increased consistency.



We partnered with SIK Golf and Bryson Dechambeau to design the most accurate putter face possible. Each aluminum face insert features SIK Golf's patented Descending Loft Technology (DLT) that utilizes four descending lofts to ensure the most consistent roll and launch angle for a variety of putting strokes and attack angles.

SIK Golf's patented Descending Loft Technology (DLT) produces a consistent launch of 1.5 degrees for every type of stroke. Whether you have an ascending, neutral or descending attack angle, every putt will have a consistent launch and trajectory.
