What should be considered in the design of hand tools to prevent injuries?

The design of hand tools should prioritize grip size, weight, and angle of use to ensure that they promote ergonomic handling and minimize the risk of injuries. Grip size is crucial because it affects how comfortably a user can hold the tool; if the grip is too large or too small, it can lead to excessive strain on the hands and fingers, potentially causing musculoskeletal disorders. The weight of the tool is also important; tools that are too heavy can lead to fatigue and discomfort during prolonged use, increasing the likelihood of an injury. Finally, the angle of use affects wrist position; tools designed to allow for a natural wrist posture help reduce tension and stress during operation, further preventing injury.

Prioritizing these ergonomic factors in tool design supports better posture, reduces the risk of repetitive strain injuries, and enhances overall user efficiency and comfort.
