The Cobra Max Iron set with steel shafts feature TecFlo design; a construction technology which creates a progressive set of irons in which each club is optimized for ideal performance.
The 4 iron through 8 iron feature a half hollow design, which is a cavity with a hollow lower half, translating into a deeper center of gravity and easier launch with more forgiveness.
The 9 iron and PW have a deep cavity undercut design which removes weight from the back of the entire face area, allowing removed weight to be relocated to the perimeter of the head for more forgiveness on mis-hits.
The GW is designed with specialty wedge engineering, which translates to better performance around the greens and more ease in getting out of the bunkers.
