What defines a safe edge in a specific application?

A safe edge in a specific application is defined as an edge that has no teeth, which contributes to a smoother and less hazardous surface. This characteristic is important in various contexts, such as machinery, tools, and construction elements, as it reduces the risk of injury or damage when in contact with people or materials. Edges without teeth are typically less abrasive and do not have pointed or sharp features that could pose risks of cuts or snags.

In comparison to other edge types, a sharp and angled edge can create significant risks by cutting or puncturing surfaces or skin, while a rounded edge typically provides some level of safety but may not always be adequate depending on the context. A serrated edge is designed for specific cutting functions and can be inherently dangerous due to its teeth, which is contrary to the concept of safety in edges. Overall, a safe edge with no teeth is the best choice for minimizing potential hazards in various applications.
