This ultra-premium player's distance iron is being led by innovation breakthroughs by Tour Edge, most notably the new Diamond Face 2.0 and the VibRCor Technology that provides the ultimate in power and feel. 

Dual VibRCor Technology- The Exotics C721 Iron consists of a high-grade TPU injected into the hollow-body pocket to create new speed-inducing and feel-enhancing technology called VibRCor. 

VibRCor performance gel is injected into the hollow-body cavity to work in partnership with an extremely thin, yet light TPU layer to dampen sound and shock and to produce faster ball speed at impact. 

Full-Face Diamond Face 2.0 Technology- The iron features a full-face Diamond Face 2.0 technology; the first time Tour Edge has employed Diamond Face technology into an iron design. 

92 different diamond shapes behind the face act as mini-trampolines to create faster ball seeds and expand the sweet spot to outer areas of the face so that the full face of the iron is covered. 

Military Grade Maraging Steel- The design is a 2-piece cast body with a forged high-strength Military-Grade Maraging Steel Face that is plasma-welded onto the 17-4 stainless steel body.

This ultra-high-strength steel is used in aerospace, and other applications which require a high strength-to-weight material, allowing Tour Edge engineers to produce a significantly thinner face. 

L-Cup Face- The L-Cup Face acts as a hinge designed to create a thinner leading edge that provides a dramatic spring-effect throughout the face for incredible forgiveness on miss-hits either off the toe or the heel.

Player Preferred Shaping- The Exotics C721 Iron (Competition Spec) features a smaller, more classic shape, more traditional lofts and a thinner topline that is still ideal for a broad range of golfers.
