Tour Edge Exotics 721 Irons Preview

Tour Edge continues their rollout of their new Exotics 721 series with a brand new set of player-distance irons. The Exotics 721 iron family features brand new technology with an upgrade on their patented Diamond Face to boost ball speeds and control.


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 provide the ultimate in power and feel.

The Exotics C721 Iron features a smaller, more classic shape, more traditional lofts and a thinner topline that is ideal for a broad range of golfers.

Dual VIBRCOR Technology – The Exotics C721 Iron consists of a high-grade, ultra-light TPU (Thermoplastic Polyurethane) injected into the hollow-body pocket to create new speed-inducing and feel-enhancing technology called VIBRCOR.

The proprietary VIBRCOR TPU is strategically placed in two places within the iron to create a feel-enhancing internal technology with perimeter weighting around the entire clubhead for maximum forgiveness and power off the face. VIBRCOR performance TPU is injected into the hollow-body cavity and works in partnership with an extremely thick, yet light VIBRCOR layer to further aid the feel of the clubhead and to produce faster ball speed off the face, while dampening shock at impact.

This dual VIBRCOR treatment creates the sound and feel of a forged muscle-back iron in a sleek, extremely long and forgiving player’s distance iron design. The hollow-body design with dual VIBRCOR infusions delivers a low CG (Center of Gravity) which helps maximize launch, distance and overall playability. It also adds 12 grams of weight to the low end of the clubhead, in turn increasing deflection to create an explosive spring effect off the face.

Full-Face Diamond Face 2.0 Technology – The Exotics C721 Iron features full-face Diamond Face 2.0™ technology, the first time Tour Edge has employed Diamond Face technology in an iron.

Different diamond shapes of variable face thickness behind the face act as mini-trampolines to create faster ball speeds and expand the sweet spot to outer areas of the face. There are a total of 92 Diamond shapes featured on Diamond Face 2.0 that cover the entire face of the C721 iron. Diamond Face 2.0 features three different thicknesses in an interweaving pattern and features a face thickness reduction of 29%.

This increase in Diamond Face coverage to the extreme heel and toe dramatically increases ball speed on off-center hits. The decrease in overall thickness of the face also saved five grams of weight that was relocated to the lowest part of the clubhead.

Military Grade Maraging Steel, L-Cup Face – The design is a two-piece cast body with a forged high-strength Military-Grade Maraging Steel Face that is plasma-welded onto a 17-4 stainless steel body.

This ultra-high-strength steel is used in aerospace, with applications including landing gear, helicopter undercarriages, slat tracks and rocket motor cases and other applications which require a high strength-to-weight material. This allowed Tour Edge engineers to produce a significantly thinner face, the thinnest in an Exotics iron to date. The L-Cup Face acts as a hinge designed to improve accuracy and protect ball speed on off-center hits. The thin L-Cup Face design combined with the Military Grade Maraging Steel dramatically increases face flex across a greater surface area of the face.

 A thinner leading edge provides a dramatic spring-effect throughout the face for incredible forgiveness on miss-hits either off the toe or the heel.

Hollow-Body Technology – Tour Edge has long been a pioneer in hollow-body iron designs, translating the benefits of wood construction into classic iron designs.

This hollow-body iron design of the Exotics C721 Iron offers the best in perimeter weighting and increased face flex, plus the ability to have a thinner face and a deeper CG in a thin-sole iron design. The hollow body design creates distance and forgiveness and when combined with VIBRCOR, it achieves a player’s distance iron with the feel and control of a forged iron.

Notch Hosel  The Notch Hosel on the iron head allows for easier bending +/- 3-degrees for expert custom fitting.


SpeedTested Shafts – Every shaft in the Exotics 721 Series has been SpeedTested to find the optimal custom shaft pairing for every flex, determined by robotic testing and validated by player testing.
