In practice, you usually did not have to remove all of the sprockets at the same time, because you needed a sprocket to hold the freewheel in place while you unscrewed the one you wanted to remove. There were special vises that gripped the threads to let you take off the last sprocket, but I never found the need to use one. Another way to remove all of the sprockets is to tighten the two largest ones against each other, loosen the remaining smaller sprocket and then unscrew the largest sprockets from each other. British Cyclo freewheels were different -- all the sprockets screwed on from the left except the smallest -- and quickest wearing -- one! This sprocket was integral with the freewheel body and could not be removed. Mechanics who didn't know this have broken teeth off this sprocket trying to remove it. But that's ancient history and you will probably never see a British Cyclo freewheel!
In der Praxis war es normalerweise nicht nötig, alle Ritzel zur gleichen Zeit zu entfernen, weil man ein Ritzel benötigt, um den Freilauf in Position zu halten, während man das eine abschraubte, das man entfernen wollte. Es gab spezielle Schraubzwingen, die das Gewinde greifen konnten, damit man das letzte Ritzel entfernen konnte. Es gibt allerdings kaum jemals echte Verwendung für dieses Werkzeug. Ein weiterer Weg, alle Ritzel zu entfernen, ist es, die beiden größten Ritzel gegeneinander zu befestigen, die kleineren Ritzel zu lösen und dann die größten Ritzel gegeneinander abzuschrauben.

Newer freewheels use splined sprockets: you need only unscrew one or two outer sprockets, and then the others slip off. Shimano Hyperglide freewheels use all splined sprockets, with a threaded lockring similar to the system used on Hyperglide cassette hubs.
