Mizuno describes their new MP-5 as a forged iron like no other. Designed to sit between the existing MP-4 irons and the new MP-25's, the MP-5 is not a blade or cavity back, instead it is what Mizuno call a Channel Back iron.
This distinctive feature on the back of the club has been made possible by combining Mizuno's traditional Japanese craftsmanship with modern CAD design, marrying the best features in one clubhead.
The channel ensures that an appropriate degree of thickness remains behind the central impact point of the club to give the club the distinctive feel of a blade, whilst allowing distribution of sufficient mass around the clubhead to increase stability and performance on off-centre strikes.
The result is a clubhead that is larger than that of a traditional blade with a thicker topline, giving a more powerful look at address, but testing with Mizuno professionals and the skill of Mizuno's craftsmen has retained the sense of proportion and size that better players demand at address.
David Llewellyn, Head of Design at Mizuno, explains this fusion of tradition and technology:
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.
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.
As with all Mizuno's MP irons the MP-5's are Grain Forged from a single piece of 1025E Pure Select Mild Carbon steel to compress and maintain a consistent grain through the neck and hosel of the club to providing consistency and distance control.
