Mizuno M-Craft OMOI #5 Putter

Mallet Putter

The M-Craft OMOI #5 is Mizuno's answer to a specific problem: golfers who want the stability of a mallet but still put a little arc in their stroke. OMOI means heavy in Japanese, and that name is the whole point. Mizuno built this line with extra head weight to quiet the hands and smooth out tempo on fast greens and long lag putts.

What makes the #5 stand out is the pairing of a mallet head with mid toe hang. Most big mallets are face-balanced, built for a straight stroke. This one hangs the toe partway down, so it wants to open and close a bit through impact. If you have a natural gate to your stroke and you've always fought the dead, robotic feel of a face-balanced mallet, this is the club that meets you halfway.

It's a 2024 model forged from mild carbon steel, so the feel is soft and the feedback is honest. You'll know when you catch one thin. That's a feature, not a bug, for the kind of player Mizuno is aiming at here.

Design

Mizuno forges the M-Craft heads from 1025 mild carbon steel and mills the face and body, which gives you that dense, muted thud off the putter face that forged fans chase. The OMOI version adds mass to the head compared to the standard M-Craft mallets, and you feel that weight most on longer putts where a heavier head keeps the stroke on pace without extra effort from your hands. The #5 carries a single alignment aid to frame the ball at address, kept clean rather than cluttered with lines and dots. Mid toe hang tunes the head for a slight-to-moderate arc, and the overall shape gives you real MOI and forgiveness on off-center strikes while still allowing the face to rotate naturally through the ball.

Who It's For

• You put a slight to moderate arc in your putting stroke and dislike how dead a face-balanced mallet feels.
• You want mallet-level forgiveness on mishits but still like a putter that lets the face rotate.
• A heavier head helps your tempo, especially on lag putts and quick greens where the hands tend to get busy.
• You value soft, forged carbon steel feel and want honest feedback that tells you where you struck the ball.
• You prefer a single clean alignment aid over a busy topline full of lines and sightdots.

Frequently Asked Questions

What does OMOI mean and why does it matter for this putter?

OMOI is Japanese for heavy. Mizuno adds head weight to the OMOI models compared to the standard M-Craft mallets. The extra mass slows and steadies your tempo, which is why the #5 works well for lag putts and fast greens where lighter putters can feel twitchy.

Is the M-Craft OMOI #5 face-balanced?

No. It has mid toe hang, which means the toe droops partway down when you balance the shaft on your finger. That suits a stroke with a slight to moderate arc. If your stroke is dead straight back and through, a face-balanced mallet would fit you better.

What is the OMOI #5 made of and how does it feel?

The head is forged from 1025 mild carbon steel and milled. The feel is soft and dense, with clear feedback so you can tell a centered strike from a thin one. Golfers who like a firm, insert-style click will find this softer than they expect.

Should I choose a mallet like the #5 or a smaller M-Craft blade?

Go with the #5 mallet if you want more forgiveness on off-center hits and a heavier, more stable head. A smaller M-Craft blade gives you more feel and workability but punishes mishits more. The mid toe hang on the #5 means you don't have to give up arc-friendly balance to get the bigger head.

Does the OMOI #5 come with an alignment aid?

Yes, it has a single alignment aid to help you set the face square at address. Mizuno keeps it minimal rather than covering the topline with multiple lines, which some players prefer because it's less distracting over the ball.
