Well, for installing to an external disk you don't need special tools, but for cloning an existing install it's much easier to use Carbon Copy Cloner.

Sure, but that gives a very limited environment. Nothing to do with your usual login environment and the tools you might have available there. Even if the recovery partition allows you to mount your usual boot disk and run apps from it, that very action will make it impossible to do the kind of maintenance that requires to unmount the disk.
