Joining the popular MP line of irons from Mizuno in September is the MP-5 model. Mizuno are billing this better player iron as neither as a blade or a cavity back, but a revolutionary ‘Channel Back’ that is a forged iron like no other.

Designed for the ultimate feel and workability, and sitting neatly between Mizuno’s classic MP blades and smaller players’ cavity-backs, the MP-5’s ‘Channel Back’ design represents both traditional Japanese craftsmanship and the wonder of modern-day CAD design.

The Channel Back design keeps an appropriate degree of thickness low behind the central impact point to deliver the blade-like feel better players crave on pure strikes, while allowing sufficient clubhead mass to be relocated to parts of the head where it can increase clubhead stability and performance on off-centre strikes.

MP-5 channel backThe head is slightly larger than a traditional blade and the top line a little thicker for a more powerful look as a result of extensive testing among professionals, but Mizuno’s skilled craftsmen have cleverly been able to retain the sense of proportion and shape needed to suit the eye of better players at address.

“Marrying the skill sets of our CAD-based engineers with the more traditional craftsmen in Yoro Japan, we’re able to produce beautiful irons that play a lot more forgiving than you would imagine by looking at them,” says David Llewellyn, head of design at Mizuno. “I think Mizuno is pretty unique in still having craftsmen that worked in the era before CAD design, which means our irons have a kind of emotion and history built into them.”

MP-5 insetThrough the set the design of the Channel Back is progressive to offer the optimum launch conditions. The channel is slightly higher in the short irons to offer a more penetrating, controllable flight while in the long irons, there is more weight lower in the head to increase launch.

The MP-5 is also Grain Flow Forged, something Mizuno has been doing for 30 years that compresses and maintains a consistent grain through the neck and hosel, guaranteeing greater consistency and precise distance control.

GM Verdict
While the new MP-5 looks like a blade from every angle, they certainly offered the higher levels of forgiveness similar to that of an iron with a shallow cavity. The feel was absolutely superb, something you come to expect from a Mizuno iron, slightly firmer than the true blade MP-4 model, but still soft enough to offer feedback on your strike and minimal vibration into the hands. At impact, the club felt stable and solid, and shots from the middle were rewarded with a strong, consistent trajectory.

The new MP-5 irons have an RRP of £115 per club and will be available from September 1st.

    Played these on the course for the first time. Never thought I’d replace my 714 ap2s, well, I was wrong.
    The long irons were easy to hit with great distance, only slightly shorter than my 714s, but the feel out distanced them by a mile.
    I had a little trouble at first honing the short wedges, but within a few strokes had found a rhythm. These have distance. Don’t be fooled. Maybe that’s why all the mizuno pros have switched to these. Easily one of the best irons I’ve played in the past 10 years. My only concern is the long term durability of the finish. After one round the soles were marked, but the faces showed zero snags (of course I used new balls).
    My lasting impression, other than the stop in your tracks beauty of the clubs, was the easy workability, unexpected distance, and ease of use. I would recommend these for mid handicappers down.
