Technical Information - Forgiveness
In golf, the terms "forgiveness" refers to the engineering and/or the design elements in golf clubs that lessen the effects of bad swings and poor contact with the ball by reducing face twisting. A golf club that has these features is said to offer “forgiveness.” and that means the club's design elements are intended to minimize the effects of poor swings and poor contact.
So, why are we telling you this? Well…hold that thought but, lets start off with some basics.
How is MOI or “moment of inertia.” or forgiveness measured? This is a measurement (grams per centimeter squared) shows how much resistance a clubhead has to twisting when a shot is miss-hit or off center. The higher the MOI reading, the more resistance it has and the more forgiving the club will play. This “forgiveness” is measured with an apparatus that provides a rating of Moment of Inertia or MOI. The rating ranges from less than 2000gm-cm2 to 5900gm-cm2 depending on which club is being measured.
A typical traditional shaped wedge has an average MOI rating at around 2600 gm-cm2 would consider that club to have a pretty good level of forgiveness.
Now, back to your question…So, why are we telling you this? Because the Cutter Wedge is without question, the highest rated MOI on the market today AND probably the highest EVER created.
Cutter Golf IZZ MOI Findings
- We measured several traditional sand wedges with an average IZZ MOI of 2603 gm-cm2 and the IZZ MOI of the Cutter 56-degree wedge is 3486 gm-cm2 which is a 26% increase in MOI or forgiveness.
- While a higher MOI exhibits a clubhead that will resist twisting more on off-center impacts the Cutter Wedge has design feature that helps to stabilize an off-center hit; it is the crescent shaped sole.
- An off-center impact on a Cutter Wedge will twist less MORE SO due to the SOLE technology. Traditional wedges are rectangular in nature from heel-to-toe which do little to help resist twisting on off-center impacts because they are naturally unstable.
Cutter Golf Center of Gravity (CG) Findings
- The vertical height of the Cutter Wedge Center of Gravity (CG) is 27.2mm high from the leading ledge. Of the several traditional wedges measured, the vertical CG height averaged 19.34mm from the leading edge. A 29% increase in CG height
- While much of the Cutter Wedge's mass appears low and in the sole its high topline contributes to shifting the CG upward as well. In physics there is a saying, "so goes the geometry goes the CG". In this instance the Cutter Wedge's topline measures 68.4mm up from the leading edge where the toe height on traditionally shaped wedges peaks around 61.2mm which equates to an 11.2% increase.
- As the Cutter Wedge's topline increases in height so does its vertical CG. Since the 2010 groove rule change by the USGA it has been proven that increasing the vertical CG height of higher lofted clubs (wedges) results in increased spin. The Cutter Wedge's vertical CG is likely the highest in the industry and subsequently contributes to increased spin and quicker launch.
