The common coffee grinding knives are basically divided into three kinds: conical grinding knife, flat grinding knife and ghost tooth grinding knife.
Among these three sharpening knives, perhaps the one we have the least contact with is the ghost tooth knife. Ghost tooth cutter, as the name implies, is like ghost teeth, seems to be at sixes and sevens. This kind of grinding can effectively avoid the fine powder often mixed in the grinding powder, and ensure the uniformity of the grinding powder, so as to ensure the taste of coffee. The one that can be easily contacted in China is the big flying eagle.
