Pre-Owned Callaway Big Bertha OS 4 Utility Iron (20.5°) – UST Mamiya Recoil ES 460 F2 Senior Graphite Shaft

The Callaway Big Bertha OS 4 Utility Iron is engineered for maximum forgiveness, easy launch, and effortless distance, making it an excellent option for golfers seeking help with long-iron performance. Featuring an oversized head design and perimeter weighting, this utility iron inspires confidence at address while promoting straighter, more consistent ball flights.

With a 20.5° loft, the Big Bertha OS 4 Utility is ideal for replacing hard-to-hit long irons, offering strong distance with a high-launching trajectory. The low and deep center of gravity helps get the ball airborne quickly, even on off-center strikes, while maintaining stability and control through impact.

This club is fitted with a UST Mamiya Recoil ES 460 F2 (63g) Senior flex graphite shaft, designed to provide a smooth feel and increased swing speed for slower to moderate tempos. The lightweight graphite construction reduces vibration and helps promote higher launch and added carry distance. Measuring 40 inches, the club offers added leverage for effortless distance and improved forgiveness.

Condition: Pre-owned – Average condition. The club shows cosmetic wear consistent with regular play, including surface scratches or face wear, but remains fully functional with no effect on performance.
