Mizuno M.Craft X Z2 and Z3: what zero torque changes in a modular putter

Mizuno's modular putter gets a new way to balance

Announced on September 10, 2026, Mizuno's M.Craft X expansion is not the launch of an entirely new putter family. It adds a Z face-and-hosel assembly intended to neutralise the head's resting torque, plus two interchangeable rear-head shapes. The reported US retail date is October 30. As of October 26, the engineering can be examined, but an independent verdict from widespread retail use would be premature.

The physics behind “zero torque”

On a conventional putter, the shaft axis and the clubhead's centre of gravity often do not coincide. Depending on orientation, that offset can produce a tendency for the head to rotate. Mizuno says the Z assembly places the shaft axis through the centre of gravity in three dimensions. Its aim is to minimise the head's preference for a particular resting orientation, rather than merely making the toe hang up or down.

The distinction matters. “Zero torque” describes a particular balancing geometry; it does not mean a golfer's hands cannot rotate the face, that mishits exert no forces, or that every putting stroke will become straighter. Player technique, impact location, grip pressure and ball speed remain important. No universal strokes-gained improvement should be inferred from the design claim.

Two silhouettes, one modular platform

The Z2 uses a broad Triple Wide profile that resembles an enlarged blade, while the Z3 adopts a rounded Dome Mallet body. Their appearance at address, alignment cues and distribution of mass differ. A golfer comfortable with a traditional blade may prefer the Z2's presentation; another may find the Z3 easier to frame behind the ball. Neither preference establishes a performance winner without measurement.

The line's modular design is a more substantial engineering story than the styling. Mizuno now lists four neck configurations—Zero Torque, Plumber, Slant and Bend—and five back shapes. That gives 20 neck/body combinations before changing sole weights. Mizuno advertises more than 100 total build options when weights are considered. Those are possible configurations of a system, not 100 individually launched putter models.

What the official specifications confirm

Mizuno's US specifications list Z2 and Z3 at 3° loft, 70° lie and 34- or 35-inch length, with onset rather than traditional offset. The listed shaft is KBS CT120 and the Zero Torque grip is the SuperStroke Zenergy TLT Off-Axis. The manufacturer lists the Z configurations as right-handed only on its US page; options may vary by region.

Construction combines a forged 1025 steel body, CNC-milled face and milled aluminium back section. The configurator shows replaceable sole weights of 7, 14 and 21 grams. Weight, head size and torque balancing each influence a different aspect of feel or stability; they should not be treated as interchangeable explanations of one claimed benefit.

Price, timing and a useful test

GOLF.com's September 10 report lists $399.99 for a complete Z putter and $149.99 for either newly introduced rear section. Pre-orders reportedly began on September 9, with retail availability scheduled for October 30. These are US figures, not worldwide guaranteed prices.

The practical test is to compare a player's existing putter with both Z shapes on repeated short and long putts. Measure face angle at impact, strike dispersion and distance control rather than judging only a few successful putts. A modular build is valuable if a fitting identifies a repeatable preference—not simply because the club is labelled zero torque.
