Best irons from Callaway golf clubs
Irons in best golf clubs are so-called because their clubheads are made of metal. Of course, "woods" are now also made of metal, but that's a relatively recent development. Irons have featured metal clubheads (steel, these days) for centuries.
Irons feature thin clubheads and grooved faces. Accomplished players might choose a "muscleback" or "blade" style of iron, whereas beginners and most recreational players will want a "cavity back" style.
The difference is that a blade-style features a full back on the rear of the clubhead of wholesale golf clubs, whereas a cavity back is exactly that: the rear of the clubhead is, to a certain degree, hollowed out. This creates an effect known as "perimeter weighting," which is helpful to less-accomplished players.
A typical, off-the-shelf set of irons will include a 3-iron through pitching wedge (advertised as "3-PW"), 8 clubs total. The TaylorMade golf clubs are identified by a number (or "PW") on the sole of each club.
Each club has a little less loft than the next and a little longer shaft length than the next, so each club goes a little farther than the next. That is, a 3-iron has less loft than a 4-iron, which has less loft than a 5-iron, and so on. Also, a 3-iron in Callaway golf clubs is a little longer than a 4-iron, which is a little longer than a 5-iron, and so on. Therefore, a 3-iron will go a little farther than a 4-iron, which will go a little farther than a 5-iron, on through the pitching wedge.
The yardage gap between irons is generally 10-15 yards. Your 3-iron, in other words, should produce shots that are 10-15 yards longer than your 4-iron with Ping golf clubs.
Also, as you move through the set to the shorter, more lofted clubs, the resulting shots will have a steeper trajectory; shots will rise at a steeper angle and fall at a steeper angle.
