Because the sand wedge is a separate category in the classification of clubs, it does not need full swing, but needs more swing skills. The angle is larger than that of iron, the weight is also larger, and the most important thing is that the bottom surface has characteristics-the rebound angle is larger.

If we put the sand wedge flat on the flat ground and hit the ball, the trailing edge of the bottom of the stick touches the bottom surface, and the leading edge is inclined, so the angle formed by the bottom surface of the stick and the flat ground is the rebound angle.

The rebound angle of bunker wedge is related to the quality of bunker ball handling and ball cutting at the edge of green. When the bottom of the bunker rod hits the sand below, its rebound angle will prevent the club head from sinking too deep into the sand. The same bounce angle will also play a role in too long grass or fairway.

The angle of rebound angle varies from 0 to 20 degrees (the sand wedge is marked with the reading of rebound angle), which is suitable for different court conditions. Generally speaking, a higher rebound angle is suitable for soft sand or wet and soft fairway.

The width of the bottom surface of the bar will also affect the role of rebound angle. The wider the bottom surface, the more the bouncing effect can be increased, and the less likely the club head will fall into the sand.

face angle

The face angle refers to the direction of the face of the wooden pole. The face direction of most wooden poles is the hitting target area facing forward, which is called natural face. Others are slightly to the left or slightly to the right, which is called opening face or closing face. The degree of opening or closing is the surface lead angle.

The closing or opening of the hitting face of the wooden club head is likely to lead to a left curve ball or a right curve ball, which is an important factor affecting the hitting direction or correcting the fairway.

Under normal circumstances, it is best for golfers who often play the right curve to choose a wooden club head with a closed face. At present, the general wooden poles are all closed. Whether you like this face shape or not, it is absolutely effective.

Professional players, because of their fast swing speed and fast hook path, are suitable for choosing wooden poles with an open face of 0.5 degrees.

There is no such thing as a hard core.

Rod neck angle

When the bottom of the golf club head is close to the ground, the angle formed by the ground plane and the neck of the club head is called the neck angle, that is, the angle formed by the shaft and the ground in this state. Some people say that the face angle and neck angle are as important as a person's second pulse.

The angle of the club neck mainly affects the direction and accuracy of hitting the ball. Different clubs need different neck angles to ensure the accuracy of hitting the ball. If the neck angle doesn't match your body shape, posture and swing, you will hit the ball badly.

Every time we hit the ball, the bottom of the club should be parallel to the ground, so that the ball will fly directly. If the toe of the club (the front end of the club head) is inclined, the ball may not be sweet, resulting in left pull. We call this club too steep, so we should lower the angle of the club neck, that is, make the angle of the club neck smaller.

On the other hand, if the heel is tilted when hitting the ball, the ball will tilt to the right and the angle of the neck will be adjusted a little.

Plane inclination lofting

The inclination of the face is the most important factor of the club. Screwdriver, iron wooden pole and special sand wedge are clearly marked with plane inclination, but iron bars are rarely marked. That is, the angle between the club face and the vertical line of the ground.

The inclination angle of the club face can control the ball speed, take-off angle and backspin, and determine the flying angle and distance of the ball.

Each club has a different face angle, so different clubs can hit different distances. Even if the length of the whole set of clubs is the same, the golf equipment will be obviously different as long as the face angle is different.

The smaller the angle, the lower the trajectory and the farther the distance; The larger the angle, the higher the trajectory. Usually, the face inclination of No.5 iron is 28 degrees, the angle difference between two adjacent clubs is 4 degrees, and the distance difference after hitting the ball is 10~ 15 yards. Generally speaking, the angle difference of continuous clubs should not be less than 3 degrees and should not be greater than 5 degrees.

How far the club can be played depends on everyone's swing speed, as well as the face angle and take-off angle caused by the first two.
