[Tool] Path Tool [Description] 
Technically, this tool is not a selection tool, however it creates paths - which can be turned into selections. This tool allows you to draw around the edge of any object on your image. More importantly, it provides you much more control than the other selection tools when working with complex shapes. Similar to the Intelligent Sissors, the Path tool results in control points that you can move around as required.
