A rounded head on a sledgehammer indicates what?

A rounded head on a sledgehammer is indicative of potential harm to users. The design of a sledgehammer, especially with a rounded head, suggests that it is intended for striking with great force and impact. This type of head can lead to more uncontrolled swings and strikes, increasing the risk of accidents, particularly if used improperly or if the user is not adequately trained.

While certain design features may aim to improve effectiveness or safety in some tools, a rounded head can create a false sense of security about safety. As users might expect that the rounded surface would be safer, they may underestimate the damage it can cause in various situations. Therefore, understanding this aspect of the design is crucial for anyone handling this tool.
