What is a common effect of using dull cutting tools?

Using dull cutting tools typically leads to more stress on the user due to the increased effort required to perform tasks. When tools are not sharp, they demand greater force to cut through materials, which can lead to fatigue and discomfort for the operator. This additional exertion not only makes tasks more arduous but can also increase the risk of accidents, as the user may struggle to maintain control over the tool.

In contrast, sharp tools are designed to cut efficiently and require less physical exertion, allowing for smoother operation and reducing the likelihood of mishaps. The other options do not align with the typical outcomes associated with dull cutting tools. For instance, dull tools negatively impact efficiency and precision, leading to poor results and longer job completion times, rather than increasing safety or enhancing effectiveness.
