What's the difference between labor tools in the past and now?

In the past, labor tools were relatively unskilled and were very traditional tools. In the past, the efficiency of using labor tools was relatively low, and it was impossible to produce more labor tools, because the conditions were limited and the labor tools in the past were very backward. Nowadays, labor tools are more practical and efficient, and can adapt to modern labor work. The previous labor tools paid attention to usability, but they were not used. Nowadays, labor tools pay attention to how to better use them in work and improve efficiency.
