Compact profile for launch and trajectory control for more distance. Slight offset for more aggressive players that engage the turf.

The small head size is controllable from any lie.

Center of Gravity Design
Low center of gravity with enhanced operability.

High-strength steel cup face

This strong and high trajectory model makes it easier to aim for the greens.
In the past, golfers could not get fit for UT clubs. Now you can.

112cm³ head emphasizing the smooth swing and the great control performance.

  • The ball rises easily and travels straight.
  • For golfers wanting solid feel, good spin and a high flight.

Comparison between TW737 UT and TW737 UTc

UT·IRON / Ligthweigth

Ligthweigth zone shaft in which the needs of females and golfers who need a lighter option.

This is a shaft that responds to the needs mainly to golfers  who want to launch the ball high and take dead calm.
By laminating the Nickel-Titanum alloy, a shape-memory alloy, at the leading end ensures the design will prevent poor performance of an off-center shot.
