Cavity Back C1 Tour
The C1 Tour has the forgiveness of a cavity back iron, and the thin topline and sole of a blade for control and workability. It's forgiving enough for recreational golfers, and accurate and workable enough for several players on the Tour.
The Benefit of Cavity Back
The forgiveness of a well-designed cavity back is incomparable. The cavity behind the face distributes the weight around the edges of the clubface. This separates the mass of the club from its center of gravity.
The benefit of this separation is less club twisting about the center of gravity axis when the ball is not hit directly at the sweet spot. This reduction in torque allows off-center shots to stay straight.
Too much perimeter weighting however has a tradeoff. If the ball goes straight regardless of the swing, there is less workability to induce a draw or fade. The moderate cavity back of the C1 Tour irons was designed for golfers who want to work the ball to shape their shots, but not let mis-hits get away from them.
Soft 3430 Steel
3430 Stainless steel is a soft and responsive type of steel. It is an excellent material for both investment casting and hot-temperature forging (ie a "form-forging" process).
Coupled with a thin top-line and sole, the 3430 Steel of the C1 Tour offers a uniquely soft feel with a precise amount of feedback. The thin 3430 face causes the ball to jump off the face sooner. This enhances both the feedback and the ability of the golfer to intentionally fade or draw the ball.
CNC-Milled Irons
While many wedges and putters go through a CNC-milling process to flatten the surface of the face, almost no manufacturer does this expensive process for irons.
Wedges and putters need CNC-milling for accuracy and the ability to induce backspin. In a wedge for example, U-grooves with highly precise specs need a perfectly smooth surface in order to "bite" into the ball. This can only be accomplished with a CNC-milling process.
This same precise workflow of CNC-milling and U-grooving is applied to the Alpha C1 Tour irons. They are one of the few club manufacturers to offer CNC-milled irons.
