As the saying goes: "The pointed knife is long like a writing brush, broad like a chive leaf. Those slightly smaller number two. The sharp edge aligns with the flat end. The sharp edge is used for cutting, scraping, and carving; the flat end is used for pressing, smoothing, stroking, and pushing. For all seam connections, depth and shallowness, positioning high and low, the sharp and flat edges work together. This alone requires diligence."[1] "Chǐ" (铺) refers to the reed in a lock mechanism; here it describes a very thin blade. The pointed knife is long like a writing brush and broad like a chive leaf. One end is sharp and the other is flat and straight. The sharp side can be used for cutting, carving, and incising, while the flat side can be used for pressing, stroking, and pushing the clay body. It is the primary tool for joining and shaping. Old fish money knives are typically not discarded but can be modified into pointed knives for continued use. There are many types and forms of pointed knives, including iron pointed knives, bamboo pointed knives, through-mouth pointed knives, and curved pointed knives. **Small copper tube**: A slender metal tube used to drill the water outlet hole at the base of the spout. **Spout excavation knife**: A metal knife tool for controlling the spout holes of teapots. One end is straight and pointed, while the other end curves like a scorpion's tail. **Lid seat**: A ring-shaped base used to support the lid blank, preventing the clay body from deforming during lid production. --- [1] Zhou Rong (Ming Dynasty), *Record of Yixing Ceramics*, in Han Qilou (ed.), *Modern Translation of Ancient Zisha Texts* (Beijing: Beijing Publishing House, January 2011), p. 31.
