Last December, Mizuno released the Mizuno Pro 221 muscleback blade irons. Golfers who want forgiveness and are looking for more distance from the fairway can look someplace else, because the Mizuno Pro 221 is for accomplished golfers with powerful, repeatable swings.

Now, on the eve of the 150th British Open at St. Andrews, Mizuno has released a special limited-edition version of the Mizuno Pro 221. Your eyes are not deceiving you: They’re blue.

Only 1,221 sets will be produced, and they will be sold for $2,210 (3-iron through pitching wedge) with True Temper Dynamic Gold Tour Issue S400 shafts.

The blue plating is extremely soft, so if anyone buys a set of these irons and decides to play them, it will wear with use.

The limited-edition Mizuno Pro 221 Blue has a layer of copper over the forged steel and under the blue plating that softens feel. (Mizuno)

As with the standard Mizuno Pro 221, the clubs are forged from 1025E mild carbon steel with a layer of copper applied over the steel that softens the feel of impact. They have a narrow sole, thin topline and virtually no offset, so control-oriented players should be able to shape shots up, down, right or left.

The clubs will be available for purchase in the fall.
