Abstract
Illustrative embodiments impact tools with torque-limited swinging weight impact mechanisms are disclosed. In at least one illustrative embodiment, a swinging weight impact mechanism may comprise a hammer configured to rotate about a first axis and pivot about a second axis different from the first axis, the hammer having a void formed therein, and an asymmetric anvil disposed partially within the void, the asymmetric anvil being configured to rotate about a third axis when impacted by the hammer. The asymmetric anvil may comprise a cylindrical body and a lug extending outward from the cylindrical body. The lug may include a first impact face extending along a first plane that intersects the third axis and a second impact face extending along a second plane that does not intersect the third axis, where the second plane intersects the first plane along a line that passes through the cylindrical body of the asymmetric anvil.
