For work in such winding corners you need a small, flexible and in any case powerful device: a lawn trimmer from Kärcher. This contains a twisted cutting thread, which is constantly readjusted by automatic thread feed on the thread spool. This means that the perfect length of trimmer thread is always available for every cut, and clean cutting results are guaranteed. Particularly pleasant is that the work is very quiet and the thread spool can be changed without tools in a few simple steps. And on you go, on the trail of the last blades of grass.
