What safety feature was added to tools for convenience but is considered unsafe?

The trigger lock is a safety feature designed to prevent accidental activation of power tools when they are not in use. While it serves an important purpose in helping to ensure that a tool does not turn on unexpectedly, it can also create a false sense of security. Users might mistakenly believe that with the trigger lock engaged, the tool is completely safe to handle or transport. This can lead to neglect in following proper safety protocols, such as ensuring the tool is unplugged or powered down.

The convenience of being able to lock the trigger may encourage users to leave the tool unattended for brief moments or to carry it around without fully adhering to safety guidelines. If users do not develop consistent habits of treating tools with caution, even with the safety features, they may inadvertently increase the risk of accidents or misuse. Therefore, while the trigger lock adds a layer of safety, it can paradoxically lead to unsafe practices if not used in conjunction with proper awareness and care.
