Reaming tools for reaming a borehole and related systems and methods are described herein. In an embodiment, the tool includes a body having a central axis, and a plurality of blades. Each of the plurality of blades includes an uphole section that extends in a first helical direction, a downhole section that extends in a second helical direction that is opposite the first helical direction, and an arcuate central section that continuously extends from the uphole section to the downhole section. The plurality of blades are eccentric about the central axis such that the reaming tool is configured to pass axially through a first diameter and is configured to ream a borehole to a second diameter that is greater than the first diameter when the tool is rotated about the central axis in a cutting direction.
