Custodian Engineer Tools Practice Exam

The key idea is using a tool that multiplies your force for prying and nail removal. A flat crowbar fits this role because its long handle provides a strong lever arm, and its flat, robust blade can slide under nail heads and pry them out. The longer the handle, the more leverage you have to lift and extract nails with less effort, which is exactly what makes it a high-leverage nail puller and a versatile general-purpose lever in construction tasks.

The other options don’t serve this function. Nail drivers (whether cordless or pneumatic) are designed to drive nails with power, not pull them, so they don’t provide leverage for extraction. A paddle bit set is for drilling holes, not prying or nail removal.
