Golf knowledge: What does a set of golf clubs include?

Golf clubs are the basic equipment in golf, consisting of a ball head, a shaft, and a grip. According to the different uses of the clubs, and the clubs are designed with different club head shapes and shaft lengths, golf clubs can be roughly divided into woods, irons, wedges and putters.

There is also a club that is between irons and woods, called hybrid clubs, also called iron-wood clubs.

1. Wooden poles

Why wooden poles are called wooden poles is because the club heads in the past were mostly made of wood. The earliest ones were made of tomato wood. Because wood will swell when exposed to water, in the early days, golf clubs were sent to pro

shops for maintenance after use on rainy days; later, they evolved to be made of different materials. Iron, stainless steel, carbon fiber, and titanium are all used.

The most popular club material should be titanium. In addition to requiring no time-consuming maintenance, titanium metal has a strong rebound effect and can be hit farther. Many golf courses today cannot increase the distance, so there are certain specifications for the rebound coefficient of the woods used by professional players. The USGA stipulates that the rebound coefficient should not be greater than 0.83.

In addition to the driver 1 for teeing off, there are 3, 4, 5, 7, and 9 fairway woods. For girls, 3 and 4 wood are more difficult to hit, so the 7 or 9 wood with a higher elevation angle is introduced.

Woods are the longest clubs in a golfer's bag and have a bulbous head. Wood clubs are mainly used for tee shots. If you can use it to hit the ball very far on the first shot, it will undoubtedly take a decisive first step to complete a hole with as few strokes as possible. Therefore, the function of the wood is to gain distance. In order to increase the club head speed when hitting the ball, the swing arc should be increased as much as possible to increase the amount of impact.

2. Iron rods

Usually made of stainless steel or soft iron, there are two production methods: casting and forging. Irons are mostly used on the fairway or when teeing off on par-3 holes. The main thing they pursue is stability rather than distance.

The average seven-iron distance for men is 150 yards, and for women, it is about 100 yards. The irons included in the set are: No. 2 iron - No. 9 iron, P rod and S rod. Some brands (such as HONMA) also have No. 10 iron or No. 11 iron.

Women rarely use the 2-iron, and usually start with the 4-iron or 5-iron. From a distance perspective: irons 2, 3, 4, and 5 are long irons, irons 6, 7, and 8 are mid-irons, and irons 8, 9, P, S, and A are short irons.

3. Wedges

P, S, and A are the English abbreviations of wedges. They all belong to the category of short clubs and are also called special irons. Its characteristics are that the iron body is shorter, the swing weight is heavier than the iron club, the club face has a large inclination angle (45-60 degrees), and a rebound angle. Mainly used around the green and when saving shots in bunkers or rough. Wedges are classified according to their characteristics: pitching wedges (PW), relay wedges (GW), sand wedges (SW), and lob wedges (LW).

PW: Its angle is usually 45-49 degrees, and the hitting distance is: about 110 yards for men and about 90 yards for women;

GW: Its angle is usually 49-54 degrees. , the hitting distance is: about 100 yards for men, about 85 yards for women;

SW: Its angle is usually 54-57 degrees, the hitting distance is: about 90 yards for men, about 80 yards for women;< /p>

LW: Its angle is usually above 57 degrees, and the hitting distance is: about 65 yards for men and about 60 yards for women.

So, if you choose a 48-degree PW and a 56-degree SW, it’s best to add a 52-degree GW, which will be enough to deal with anything that may happen around the green. situation.

4. Putter

The putter is a specialized club used to push the ball towards the hole on the green. The putter shaft is short and the club face angle is the largest. No more than 5 degrees. There are mainly two types: strip shape (also called knife back shape) and mallet shape.

The earliest putters were mostly designed to be L-shaped. There are also a few professional players who still use the traditional L-shaped putter. Later, the PING Putter developed into two balls or even three balls, horseshoe-shaped cones, and various A putter that feels balanced.

5. Ironwoods

Ironwoods are clubs between irons and woods. They are called hybrid clubs and also called ironwoods.

Iron irons are divided into long, medium and short irons. Long irons usually refer to No. 3 and No. 4, 5, 6 and 7 are medium irons, and short irons are 8, 9 and 10. Fewer and fewer people use long irons, and most use chicken legs instead. Long irons are usually not easy to hit high and are prone to slices. Long irons come in handy when encountering strong headwinds due to their small angle.

The designs of iron eucalyptus ball heads are divided into blade-back type and concave-back type. The blade-back type has a higher center of gravity and is less likely to feel the club head releasing; while the cavity-back type has a lower center of gravity, and some even The center of gravity is ultra-low, the bottom is heavier, and the sweet spot area is larger, so it is easier to hit the ball and it can also be hit higher.

The concave back type is often seen on the market. The short game also includes pitching wedge (P), wedge (A), and sand wedge (S). Professional players are usually more particular about the short game, and they also subdivide different angles, 52 degrees, 53 degrees, and 60

< p> degrees and so on. Different angles can produce different ball heights and different degrees of spin.

For amateur players, wedges and sand wedges are usually shared equally. No. 10 is approximately equal to P, and No. 11 is equal to A (larger angle).
