M.Craft OMOI 04

The M.Craft OMOI 04 is the 2023 entry in Mizuno's OMOI line, built as a squareback mallet with the extra mass the OMOI name promises. Golfmonthly.com reports the head carries up to 28g more than the original M.Craft putters, and teeboxgolf.com.au reports the same figure in near identical terms. That added weight is the whole premise of the release, and it shows up again in the sole weight kit: teeboxgolf.com.au lists a pair of 8g heel and toe sole weights, while golfmonthly.com describes two 8g weights standard with a kit offering 3g or 13g options for tuning feel.

Where the sources get less tidy is the shape itself. Teeboxgolf.com.au variously describes the 04 as a wide-bodied squareback blade, a timeless full-bodied mallet, and a compact winged mallet, three descriptions that don't obviously belong to one head, while golfmonthly.com settles on a square-back design with an elongated sight-line. The neck and offset entries from teeboxgolf.com.au show the same scatter, listing plumber's neck, center shaft, and slant neck hosel options alongside full-shaft, half-shaft, and minimal offset readings. Toe hang comes in at 40 degrees per golfmonthly.com, close to teeboxgolf.com.au's 40˚, though that same source also lists 35°. Read as a family of options across the OMOI line rather than one fixed spec, and the picture makes more sense than it does as a single putter's numbers.

On feel, golfmonthly's review called it a premium milled putter that offers the stability of a mallet, while producing the feel of a blade, and praised the CNC-milled 1025 carbon steel face and the interchangeable weight system for letting a player tune that feel. Community opinion echoed the praise for the premium look and confidence-inspiring shape, but pushed back on two points: the standard grip runs larger than some players will want, and at least one reviewer found the heavier 13g weight option threw putts to the right rather than helping them.
