A keen razor edge has fine teeth and tends to dig into a thumbnail ____________.

When pressed
Firmly
With a smooth, steady grip
With excessive force

The correct answer is: With a smooth, steady grip

A keen razor edge is designed for precision and efficiency in cutting, which involves making clean, controlled movements. When a razor edge has fine teeth, it is constructed to slice through hair smoothly without causing damage or pulling. When such an edge is pressed against a thumbnail, a smooth and steady grip ensures that the pressure applied is even and controlled. This technique helps to maintain the integrity of both the tool and the cutting surface, allowing for optimal performance and minimizing the risk of snagging or tearing. Using a smooth, steady grip means that the razor will glide effectively, which is crucial for achieving a good cut without unnecessary strain or excess pressure. In contrast, options that imply pressing hard or with excessive force may lead to issues such as less control over the tool and a greater chance of damaging either the tool or the hair being cut. Thus, using a smooth, steady grip is the best practice for working with a keen razor edge.
