The Mizuno M.CRAFT X B4 Putter represents the ultimate fusion of precision engineering and customisable performance. Designed for golfers seeking the perfect balance of feel, forgiveness, and adaptability, the M.CRAFT X puts complete control in your hands, allowing you to tailor your putter to your exact stroke style. The B4 model features a Bend Neck (double bend hosel) that promotes a full shaft offset and suits golfers with a slight arc to their putting stroke. Included with every M.CRAFT X is a matching premium headcover.
At the core of the M.CRAFT X is Mizuno's signature dedication to craftsmanship — a forged face and neck crafted from a single piece of 1025 carbon steel, combined with a CNC-milled striking surface and a milled aluminium back. The result is a putter that delivers the feel of a blade with the forgiveness and stability of a mallet, redefining what a performance putter can be.
The M.CRAFT X face and neck are forged from a single billet of 1025 soft carbon steel — the same premium steel used in Mizuno's acclaimed iron lineup. This single-piece forged construction eliminates seams and inconsistencies, delivering outstanding feel and immediate feedback with every stroke. The softness of 1025 steel translates into a muted, responsive sensation at impact that golfers who value tactile feedback will immediately appreciate. Compared to cast construction, the forged method produces a tighter grain structure for superior consistency across the entire striking surface.
Every M.CRAFT X face is CNC-milled to exacting tolerances after forging, ensuring precise flatness and a consistent deep-milled groove pattern across the full striking surface. This manufacturing process guarantees reliable ball speed and dependable forward roll — shot after shot, putt after putt. The deep milling also softens the feel of impact, moderating the firmness typical of milled steel faces. The result is a face that inspires confidence: responsive enough for feel players, consistent enough for those who demand repeatability.
While the face and neck are formed in heavy 1025 steel, the back section of the M.CRAFT X head is crafted from aerospace-grade milled aluminium. This strategic use of two different materials — heavier steel at the front, lighter aluminium at the rear — shifts mass to the perimeter and raises the putter's Moment of Inertia (MOI) by 15% compared to the similarly shaped Mizuno OMOI 6 model. Higher MOI means less twisting on off-centre strikes, producing more consistent pace and direction even when contact is not perfectly centred. Critically, the aluminium back does not muffle the feedback from the forged steel face, preserving the tactile experience that Mizuno players expect.
The M.CRAFT X achieves something genuinely rare: the swing feel of a compact blade putter combined with the forgiveness of a full mallet. This is made possible by a dynamically shallow centre of gravity created by positioning the heavier carbon steel component at the face and wrapping it under the sole, while the lighter aluminium sits on top. The result is a CG that is simultaneously low and slightly forward — producing a lower-spinning launch for better initial forward roll and less skidding off the face. Golfers accustomed to blade-style putters will feel immediately comfortable with the M.CRAFT X's swing weight, while also benefiting from the stability and forgiveness that a larger mallet head shape affords.
The M.CRAFT X system redefines putter customisation with three interchangeable neck styles (Plumber, Slant, and Bend), three distinct back shapes, and two interchangeable heel-toe sole weight options (available in 7 g, 14 g, and 21 g) — yielding nine unique head combinations from a single chassis. All nine combinations share a stock head weight of 365 grams, giving golfers the freedom to change shape, neck style, and feel without altering swing weight. The full weight range (from 337 g to 393 g) even accommodates overlength shafts up to 38 inches. With the M.CRAFT X, a fully personalised putter setup is achievable without purchasing multiple putters.
The Lamkin M.Craft X Sink Fit grip fitted to every M.CRAFT X is adorned with an intricate modern mosaic pattern referencing 1906 — the year Mizuno was founded. This heritage motif is not merely decorative: it is a deliberate statement that Mizuno's newest and most technologically advanced putter stands on over a century of precision craftsmanship and innovation. The same 1906 mosaic pattern is carried through to the included premium headcover, creating a cohesive, collector-quality aesthetic. The Sink Fit profile of the grip also promotes a consistent hand position for a more repeatable stroke.
