The new Morph game-improvement irons from Tommy Armour Golf are the first to combine three distinct head designs (two-piece deep-cavity, mid-cavity and blade) that transition from long irons to short irons, company officials said. The irons are complemented by three types of proprietary Rifle Flighted shafts with trajectory characteristics tailored to each head type.

The set (suggested retail price $599.99 for 3-PW) also features a center of gravity at the face that is constant throughout the set and placed below the equator of the ball to make it easier to hit the ball higher with less effort.
