What does the second knife of excavator mean?

Double knives refer to people with insufficient knowledge and low skills in a certain job.

Two knives come from masons. Bricklayers only work in summer and autumn, stay at home in winter and spring, and supply and sell radishes in their spare time. So masons have the ability to carve radish flowers, cut bricks in summer and cut radish in winter, so they are called "two knives".
