Nine snug, evenly spaced curves that march up the wall like a caterpillar mid-crawl, now in plant-based plastic with a single bevelled working edge. Because only the chamfered face contacts the clay, the tight repetition lands without smudging, every ring distinct from its neighbours in one steady pass. The mechanical rhythm somehow stays completely organic. Great for tall cylinders, pencil holders, and planters where the surface texture is the entire personality. Slow to look at, fast to make, easier than it has any right to be.
