Attention all you U.S. Open and PGA Tour wannabees: Mizuno’s new MP-58 iron is one of the first new clubs on the market to conform to the USGA’s 2010 Condition of Competition groove rule. Not only that, but this is one player’s club that is extremely playable thanks to lightweight titanium that is forged to the outer muscle, allowing for the MP’s famous feel while dramatically increasing the club’s perimeter weighting.

The MP-58 is the first multi-material forged iron Mizuno has ever produced in the U.S. But unlike a lot of high-tech, perimeter-weighted clubs, the MP-58’s ball flight is very penetrating—just what the better player demands. The thin top-line and sole will also appeal to the low handicapper, as will the rolled leading edge and elegant aesthetics.

“When you put the club down next the ball it looks like your typically beautiful Mizuno forge muscle-backed iron,” says a 5. “But a few hits of the ball—actually a few mishits—and you realize just how forgiving and playable the club is, yet it’s still very workable.”
