What is referred to by the term "kerf cut"?

The term "kerf cut" is most accurately defined as a single slit cut. In firefighting and carpentry, the kerf is the material removed by the blade during a cut, and it represents the width of that cut. In the context of firefighting, especially during operations involving ventilation or overhaul, understanding kerf cuts is essential. These cuts can facilitate the entry of air into a structure or allow for the escape of smoke and heat, which is crucial for effective fire suppression.

While other types of cuts exist, such as circular cuts or notches for specific purposes, the focus here is on the fact that a kerf cut specifically designates a cut that creates a single, narrow opening. This characteristic is important for firefighters to control airflow and improve visibility in a smoke-filled environment.
