This lesson is the beginning. We start from the basics, focusing first on the main tools for making Yixing pottery. "Tools" are implements that must be used in order to do good work. In our Yixing pottery craft, we need many, many tools. As craft requirements change, the tools adapt accordingly. These tools are generally made, processed, and maintained by ourselves. Therefore, from a technical perspective, "if you cannot make tools, you cannot make good products." To be able to maintain tools, you must first understand the requirements for using some of the most basic tool-making tools. The most basic tools referred to here are: the "bevel chisel," "carving knife" (including flat chisels, half-round chisels, rat-tail chisels, etc.), "steel saw," and "grinding knife." These are the tools we use to make production tools. > As the old saying goes: "A craftsman who wishes to do good work must first sharpen his tools." This illustrates the importance of tools. Once we have the implements (referring to tools—chisels, knives, saws) for making production tools, such as bevel chisels, carving knives, and steel saws, we must understand how to sharpen the bevel chisel, how to use and maintain the carving knife, and how to install saw blades in the steel saw. Otherwise, we cannot use these tools and cannot bring out their effectiveness. **Bevel chisel** — This is very important for making our production tools; we use it frequently to make spouts, handles, ribs, and other components. For a bevel chisel to work well, it must first be properly sharpened. When sharpening a new bevel chisel, the first opening and grinding must be done carefully. The flat surface must be absolutely flat, and the beveled surface must have no curves. When grinding, first grind the flat surface, then grind the beveled surface. After the blade angle and cutting edge are formed, polish the flat surface and it's done. The above refers to sharpening a new bevel chisel. Afterward, when sharpening the bevel chisel, you only need to first grind the beveled surface, then polish the flat surface. However, pay attention to the following points: the sharpening stone must be flat, the force applied must be steady, and the chisel edge should not be ground like a kitchen knife. When using the bevel chisel, pay attention to safety. When cutting, push forward with your shoulder and pull back with your hand, keeping the force steady. This way, you won't damage the sharp chisel edge due to excessive force, and you can safely master and use it.
