What is a consequence of using a dull blade on a straight razor?

Using a dull blade on a straight razor significantly increases the risk of cuts and irritation for several reasons. A dull blade requires more pressure to achieve a close shave, which can lead to the razor dragging across the skin rather than gliding smoothly. This dragging motion can easily cause nicks, cuts, and uncomfortable irritation of the skin.

Moreover, a sharp blade is designed to slice through hair with minimal resistance, resulting in a cleaner cut. When the blade is dull, the hair might be pulled or torn instead of cut, contributing to discomfort and a greater likelihood of skin damage. Frequent use of dull blades can lead to an overall diminished shaving experience, making it imperative to maintain blade sharpness for safety and effectiveness in grooming.
