We have a small wall (3 feet high or so) beside our driveway, made of breeze blocks or something similar, and we would like a bit (a foot?) cut off one side, to make the driveway wider. It's not a huge job (I don't think) but it would need a tool that would cut neatly down in a straight line (and a person capable of doing this). There would be no need to go inside, so social distancing would be easy.
