What is a common issue that can render a sledge ineffective?

A damaged handle is a common issue that can render a sledge ineffective because it compromises the tool's integrity and usability. The handle is critical for providing leverage and control when swinging the sledge. If the handle is cracked, broken, or otherwise compromised, it can lead to a lack of stability and control, increasing the risk of accidents or injuries during use. Additionally, a damaged handle can lead to the head of the sledge becoming dislodged, posing a safety hazard to the user or those nearby. Ensuring that the handle is in good condition is essential for the safe and effective operation of the tool.

While aspects like weight, the material of the head, or the length of the tool may influence performance or comfort, they do not directly affect the basic functionality and safety of the sledge in the same critical manner as a damaged handle does.
