What tools are commonly used for hand digging?

The correct choice includes shovels, spades, and picks among the tools for hand digging because these tools are specifically designed for manual excavation tasks. Shovels are versatile and commonly used for moving soil, while spades are more effective for digging and cutting into the ground due to their flat blade design. Picks excel at breaking up hard or compacted soil, making them invaluable in challenging digging conditions. Together, these tools provide a comprehensive set of capabilities for hand digging applications.

In contrast, tractors, backhoes, and excavators are heavy machinery used for larger excavation tasks, not for hand digging. The choice of only shovels and trowels is too limiting, as it excludes tools like picks that are essential for effective hand digging in various soil conditions. Mixers and graders are designed for different functions entirely, focusing on mixing materials or leveling surfaces rather than excavation.
