Basically, it's a pitching wedge.
That would be a pitching wedge.
3-PW is a 3 iron through to pitching wedge. 4-AW is 4 iron through to approach wedge, and approach wedge is mainly referred to as a Gap wedge as it fills the gap between a pitching wedge and a sand wedge, it is usually around 50-52 degrees of loft. The 4-AW set allows a player who maybe doesn't like long irons to have more scoring options on the shorter shots. Although it would not be uncommon for someone to have 3-PW, then a gap wedge and a sand wedge.
If the iron has an "A" on the sole, it's an "Approach" wedge, otherwise known as the "Gap" wedge. It fills the gap between pitching wedge and sand wedge. It is usually 52 degrees of loft, plus or minus a degree. It's a great asset on the course. I carry one instead of carrying a 4 iron.
They start at a 3 iron and go to a wedge, as a general rule, as you go down the set 3 iron to wedge the clubs get shorter and have more loft.

For the average amateur golfer, the standard complement of clubs is: Driver 3 Wood 5 Wood 3 Iron or Hybrid 4 Iron or Hybrid 5 Iron or Hybrid 6 Iron 7 Iron 8 Iron 9 Iron Pitching Wedge Sand Wedge Lob Wedge Putter However, the is no "standard" set, and you may find that a Gap Wedge is more useful than a Lob Wedge (Gap is between PW and SW).
A 10 iron is usually found in Callaway golf sets of irons, it is basically a pitching wedge. I have an old set of Yonex ADX irons and it has 3-10 iron with P and S wedge. The standard wedge degrees are as follows:Flop Wedge-64 degrees Lob Wedge-60 degrees Sand Wedge-56 degrees Gap Wedge-52 degrees Pitching Wedge-49/48 degrees I believe the 10 iron is around 44-45 degree. But the better question is do you need one in your bag?
An E 'iron' is actually a Pitching Wedge. It stands for Equalizer, but the loft is the same as a PW.
10 iron is used by Callaway on some of their irons. It is basically a pitching wedge.
