Angle of attack
The angle at which the clubhead approaches the ball at impact.
A shot hit towards the green with enough back spin and trajectory to stay on the putting surface.
A counter clockwise rotation of the golf ball measured in revolutions per minute (RPM). Backspin is affected by a variety of factors, including club loft, angle of attack, golf ball construction, and environmental factors. Backspin is most accurately measured using a launch monitor. Backspin that is too high can result in shorter carry distance and roll. Backspin that is too low can result in shorter carry distance and can cause instability in flight.
The angle created between the sole line of the golf club (the line from the leading edge to the trailing edge) and the ground line at address. Bounce reduces digging as the wedge interacts with the turf or sand at impact by elevating the leading edge off the ground. This elevation promotes optimal contact resulting in consistent trajectory and maximum spin.
Bump and Run
A shot around the green in which the player hits the ball into a slope to deaden its speed before settling on the green and rolling towards the hole.
A hazard consisting of a prepared area of ground, often a hollow, from which turf or soil has been removed and replaced with sand.
The curvature of the sole measured from the leading edge to the trailing edge.
Center Of Gravity (CG)
A point of mass location on the head. CG is the point the club would balance perfectly if placed on a pin point. Properly located CG results in optimal launch and spin conditions.
A low-running shot played around the greens where the ball spends more time on the ground than in the air.
The cut length of the golf club. Club length is most accurately measured without a grip as grip caps can vary by manufacturer.
The turf displaced when the club strikes the ball on a descending angle of attack.
A wedge player who has a steep angle of attack. This player tends to position the ball back in their stance and trap the ball at impact, creating a long, deep divot. This player typically benefits from higher bounce wedges, with an option to add 1 medium bounce wedge for versatility.
Is how the wedge will perform during play. Sole width, camber, and relief are all wedge design elements that determine the effective bounce of a wedge. All Vokey wedges are marked with the Effective bounce.
Fat (heavy) Shot
A shot when the clubhead strikes the turf before contacting the golf ball, resulting in poor contact and a shot that comes up well short of the intended target.
A shot from the rough or in wet conditions that reduces the amount of backspin on the ball. This causes the ball to fly farther than it might under normal conditions.
A shot that elevates quickly often traveling a short distance, stopping quickly next to your target.
A shot played with the players full speed swing, resulting in the maximum distance for that club.
The direction blades of grass grow. Pitch shots played into the grain can be some of the hardest shots in golf and can be made easier by playing more bounce.
A manipulation or removal of material from the sole of the club. A properly fit grind and bounce combination will improve turf interaction and can help lower your scores.
The horizontal scoring lines on the face of the club that help channel debris and moisture away from the golf ball and club face. Proper groove shape will promote optimal golf ball to groove edge contact, producing maximum spin.
Grips come in many different core sizes and tappers. For most players, proper grip size is indicated by the fingers on their left hand ( right handed player) slightly touching the palm when the club is gripped. Improper grip size can result in inconsistent or improper release of the golf club. Grip size can be increased by applying extra layers of grip tape below the grip. (each layer of tape adds approximately 1/64" to the grip size)
A shot played with an abbreviated swing and reduced swing speed. Many amateurs find half swings difficult to control. To help lower your score, Vokey recommends carrying 3 to 4 wedges of varying lofts to promote more full swing approach shots.
A portion of the sole closest to the hosel that has been ground down using a grinding wheel.
A portion of the sole closest to the face of the wedge.
The angle created by the club face relative to the ground line, measured in degrees. Adjusting loft strong will reduce bounce while adjusting loft weak will add bounce to the wedge. Having proper loft gaps of 4-6 degrees is crucial for proper distance gapping with wedges.
The angle formed between the centerline of the golf shaft and the ground when the club is soled in a neutral position. Having improper lie angel, especially in wedges, can result in inconsistent contact as well as missed shots left or right. This inconsistent contact can lead unpredictable shots resulting in higher scores.
A mathematical measurement of the wedge's bounce. Loft angle + Face-to-sole angle - 90 degrees = Measured Bounce Angle Measured bounce is not always the most effective way of determining the playability of a wedge because it does not take into account other variables of the sole such as grind and sold width.
Open Club Face
The heel of the clubhead leading the toe. For a right handed golfer, the face and grooves would be pointing to the right of your intended target. An open club face will tend to increase the effective bounce and loft of your wedge.
A medium trajectory shot towards the putting surface creating backspin and very little roll out.
All ground of the hole being played that is specially prepared for putting.
Ribbed or Reminder Grip
A grip with a slightly raised area (rib) running along the underside of the grip.
A grip that is uniformly round throughout the grip.
The stiffness of the club shaft, often measured in frequency. Common flexes are Ladies (L), Senior (SR or A), Regular (R), Stiff (S), Extra Stiff (X), Tour Extra Stiff (TX). Feel should be the determining factor in wedge shaft selection, followed by weight and flex. It is important to play the proper flex in sand and lob wedges, as a shaft that is too stiff can result in poor feel on partial shots.
A collection of shots played on and around the putting green, including putting, chipping, pitching, and bunker shots.
A player with a shallow angle of attack. This player will pick the golf ball off of the turf leaving little to no divot. This player typically benefits from medium bounce wedges, with an option to add 1 low bounce wedge for versatility.
The bottom of a club designed to contact and interact with the turf.
The curvature of the sole measured from the toe of the club to the heel of the club.
The width of the sole of the club head measured from the leading edge to the trailing edge. Wider soles often increase the effective bounce of a wedge while narrower soles often decrease bounce.
The measurement of a golf club's balance point between the club head and grip. This number is used to describe how balanced the club will feel throughout the golf swing. This measurement is taken using a calibrated swingweight scale. Swingweight is written in a letter/number format. Common swingweight measurements include D2, D3 and D5. Swingweight and Total weight are often incorrectly used interchangeably.
The actual weight of the club measured by a standard weight scale. Swingweight and Total weight are often incorrectly used interchangeably.
A portion of the sole farthest from the hosel that has been ground down using a grinding wheel.
Thin (skulled) Shot
A shot when the golf ball is struck with the leading edge of the golf club, resulting a low-running shot. Several factors contribute to a thin shot including improper club length, too much or too little bounce,or improper angle of attack.
A measuring device designed to track club and golf ball data using Doppler radar technology. This data includes spin, launch angle, angle of attack and distance.
Trailing Edge Grind
A portion of the sole farthest from the face of the wedge.
The height and angle the ball travels when struck. Trajectory is best measured using a measuring device.
Up and Down
The act of taking two strokes or less to get the ball into the hole when your ball is resting off the green or in a greenside bunker.
A fitting philosophy designed to ensure consistent carry distance and degree range between clubs. It is recommended to have between 4-6 degrees of loft and/or 10-15 yards of gap between your wedge lofts.
