Manufacturing a soft, forgiving players iron in a cavity-back shape is a difficult engineering challenge. However, Cobra found a way through a metal-injection molding process to create each iron in the set—something the company previously used only for its wedges. The metal-injection molding process is beneficial for two reasons. First, it eliminates the need to hand polish the heads, which can lead to slight inconsistencies. Second, the blend of 17-4 stainless steel (80 percent) and 304 stainless steel (20 percent) goes through a sintering heat-treatment process that is nearly 150 degrees hotter than conventional forging. Not only does this provide a soft feel, but it creates a tighter grain structure to deliver the type of consistency this category demands. Cobra has made another change that better players will likely welcome: The long irons have a slightly shorter blade length with a tungsten weight in the toe area to position the center of gravity behind the sweet spot. Finally, the Lamkin Crossline grips come equipped with Cobra Connect powered by Arccos, giving users the ability to track and access a variety of shot data via the Arccos Caddie app. Read more >>
