In recent years, we've seen equipment manufacturers create so-called hybrid sets, combining irons with hybrid irons to eliminate long irons and, hopefully, improve performance through the bag.
Cobra Golf does something in that vain with its new F6 line of irons, effectively offering four types of irons in a single set. The company dubs the configuration its TECFLO (Technology Enhanced Cavity Feel Launch Optimization) system. Long irons (3-5) have a fully hollow construction. The mid irons (6-7) are half hollow construction. The short irons (8-iron to PW) have a a deep undercut cavity-back design, while the gap and sand wedges have a traditional muscle back shaping.
The company has also removed 10 grams of weight from the hitting zone, lowering the center of gravity on the irons. The wedges actually have a higher center of gravity for better control of scoring-shot trajectory.
The Speed Channel undercut on the sole allows the club to flex at impact, delivering more energy to the ball.

The entire set features milled faces and grooves, with V-grooves on the long irons (for less spin and more distance), U-grooves on the mid- and short irons and wedge-specific grooves on the gap and sand wedges.
The Cobra Golf King F6 irons will be available as an eight-piece set on Jan. 15, 2016 for $800 in steel shafts, as well as a combination set of six irons and two adjustable hybrids in steel for $900 and graphite shafts for $1,000.
