I have several anti-reverse fly reels.
The Fenwick World Class Reels are anti-reverse. I had the World Class 6 and 8, and still have the 6. I also have several Seamaster Mark III Dual Mode reels that are direct drive anti-reverse fly reels.
The reason for these reels is that you can literally have your fingers broken if you get them in the way of a spinning handle when fighting a Tarpon or Tuna. I know of a surgeon that did break his fingers while salt water fly fishing.
