As an ordinary food waiter, you need to know how to cut simple silk and chips, simple flower knives, cross knives, wheat ear flower knives for processing squid and pork loin, and how to cut water flower knives, such as fish-flavored eggplant dragon. If you are in a high-end restaurant, you should not only be good at knives, but also know how to set plates, sharpen edges and carve flowers.
