context_page_description: A golf club is a club used to hit a golf ball in a game of golf. Each club is composed of a shaft with a grip and a club head. Woods are mainly used for long-distance fairway or tee shots; irons, the most versatile class, are used for a variety of shots; hybrids that combine design elements of woods and irons are becoming increasingly popular; putters are used mainly on the green to roll the ball into the hole. A standard set consists of 14 golf clubs, and while there are traditional combinations sold at retail as matched sets, players are free to use any combination of 14 or fewer legal clubs.
  An important variation in different clubs is loft, or the angle between the club's face and the vertical plane. It is loft that is the primary determinant of the ascending trajectory of the golf ball, with the tangential angle of the club head's swing arc at impact being a secondary and relatively minor consideration. The impact of the club compresses the ball, while grooves on the club face give the ball backspin. Together, the compression and backspin create lift.
context_section_description: Irons are clubs with a solid, all-metal head featuring a flat angled face, and a shorter shaft and more upright lie angle than a wood, for ease of access. Irons are designed for a variety of shots from all over the course, from the tee box on short or dog-legged holes, to the fairway or rough on approach to the green, to tricky situations like punching through or lobbing over trees, getting out of hazards, or hitting from tight lies requiring a compact swing. Most of the irons have a number from 1 to 9 (the numbers in most common use are from 3 to 9), corresponding to their relative loft angle within a matched set. Irons are typically grouped according to their intended distance (which also roughly corresponds to their shaft length and thus their difficulty to hit the ball); in the numbered irons, there are long irons (2–4), medium irons (5–7), and short irons (8–9), with progressively higher loft angles, shorter shafts, and heavier club heads.
  As with woods, ’irons’ get their name because they were originally made from forged iron. Modern irons are investment-cast out of steel alloys, which allows for better-engineered ‘cavity-back’ designs that have lower centers of mass and higher moments of inertia, making the club easier to hit and giving better distance than older forged ’muscle-back’ designs. Forged irons with less perimeter weighting are still seen, especially in sets targeting low-handicap and scratch golfers, because this less forgiving design allows a skilled golfer to intentionally hit a curved shot (a ’fade’ or ’draw’), to follow the contour of the fairway or ’bend’ a shot around an obstacle.
