From time ti time I have to clear up carpets of moss which accumulate very fast on my paths. I generally use a dutch hoe to do the job. It works ok but is noisy and the blade tends to catch on slightly uneven blockworks. Yesterday I had a brain function, and instead of using the hoe, used a rake (the sort with springy steel teeth) but up side down. It was so much easier. The teeth glide over the surface smoothly (and relatively quietly) without snagging, and any moss (and weeds) get sliced just like that on the push cut, almost like you have a horizontal row of those safety cutters they use to cut seat belts. It made a previously tiresome task far pleasanter. Just thought I'd pass it on
