Bend Modifier.

The bend modifier is found in the modifer list when the object has been turned into a Editable poly.
The uses for this tool are limited but its results are faster then the other methods of achieving the same thing.
The bend modifier bends a selected section without the need for more Vertex's. How ever adding more vertex will add greater

This tool requires a bit of fiddling with to get the results you want as sometimes if you have the wrong selection tool up it will deform an object.

The use i found for this tool was during a tutorial where we made a basic lam post, and used the bend modifier to get a curv just before the head.
