S3 E9

  - Cobra
Introduced in 2011, the Cobra S3 steel irons and wedges combine "E9 Face Technology" with a multi-material design to optimize performance in each club. Also in the design are a progressive cavity that changes the shape of the sweet spot from elliptical in the long irons, to an oval shape in the mid-irons, to a circle in the short irons.

This club is geared toward players looking for a larger sweep spot, increased distance, and accuracy.
