Four knife and six knife refer to the juicer blades used to cut fruits or other things in a juicer. Four blades refer to four juicer blades in a juicer, while six blades refer to six juicer blades. During use, the juicing effect of different foods varies. Some users may use a juicer to crush the ice, in which case the six blade juicer will crush the ice finer. If you want to crush slightly larger fruits, the blades of a four blade juicer should be faster.

Therefore, there is no need to choose juicer blades with more leaves when juicing. Because more blades can make things worse, it's better to choose the appropriate size of juicer blades for the juicer.
