9 Iron has the most loft and least distance. 3 iron has the least loft and most distance.
The number relates to the loft of the club and the length of the shaft. For example a 3 iron has the lowest loft and longest shaft. A 7 irons has more loft and a shorter shaft than the 3 iron.
The loft on the Slingshot irons as well as any other iron ranges from 14 degrees to 60 degrees.Specifically, the Nike Slingshot 4D irons specs are as follows.Club456789PWSWLoft2326303438424655Lie61626363.56464.56565.5Length38.7538.2537.7537.2536.7536.253635.75Womens Length37.7537.2536.7536.2535.7535.253534.75HandRH/LHRH/LHRH/LHRH/LHRH/LHRH/LHRH/LHRH/LH
Normally the loft of a 7 iron.
A 3 wood has about 15 degrees of loft, a 3 hybrid has about 21 degrees of loft. A hybrid is a blend of a wood and an iron. The 3 wood would have a longer shaft than the 3 hybrid.
protractor
Two things, primarily: 1. The 3-iron has a longer shaft (the skinny metal part between your hands and the clubhead) 2. The 3-iron has less loft, meaning that the ball doesn't fly as high as with a 9-iron. I don't recall exactly but I think a 3-iron has about 21 degrees of loft compared to maybe 48 degrees for a 9-iron. These two things make the 3-iron hit the ball much farther than a 9-iron, maybe 200-225 yards vs. 100-125 yards for the 9-iron. But it is also a much harder club to make good contact with, due to the longer shaft and lack of loft.
7 iron
According to several places a club with a 19 degree loft could be anything from a 4 wood to a 3 iron. So basically it might be a 4 or 5 wood as well as a 3 iron especially if its a 3 iron hybrid.
A 9 iron is shorter, and has a little more added loft to it, so you can hit the green and not go over. A 7 iron is a mid iron, and is a little longer, and the loft is less than a 9 iron so you can have a little more added distance than a 9.
7.4 degrees
A 3 iron has a long shaft, of around 38-39 inches. It has a very compact head and a relatively loft of around 21 degrees. It is known as a long iron, a player will hit this iron around 200+ yards.
