What Titleist Say:
U•505 is designed to allow you to reclaim your long iron game. Drawing on input from Tour Pros, it provides the high, explosive launch of a utility but with a refined design that offers a more iron-like look, feel and sound.

Features & benefits:

• Speed that feels amazing - With a thinner forged L-Face and the infusion of Max Impact technology, U•505 are now Titleist’s fastest utility irons. Even better, a new
  reconfigured hollow body and core support structure ensure that dynamic speed generation now comes with superior feel and sound.
• Better tungsten for better launch -  Utilizing denser D18 tungsten weights and a 2000ºF brazing process used in aerospace construction our engineers were able to
  concentrate weight more efficiently and be even more precise with CG placement. In U•505, that meant sliding it lower and towards the heel where Tour Pros felt it
  improved launch dynamics the most.
• Utility in tour form - Based on player input, we designed U•505 with a shorter blade, shallow face and a wide sole to maintain maximum versatility while moving towards a
  look that feels more in line with the rest of the clubs in your bag.
• Tuned to perform - Even the Engineered Muscle Plate that seals the U•505 is designed to provide superior performance. The plate’s specific composition and structure help
  tune acoustics and vibrations to produce a more satisfying sound and feel at impact while also allowing weight to be shifted for precise CG.
