Abstract
Disclosed embodiments may relate to devices or tools for diverting flow within a wellbore. For example, disclosed tool embodiments may allow for more efficiently cutting and pulling of casing from a wellbore during well abandonment operations, since diverting fluid flow as disclosed may allow for a single tool string trip to allow the flow patterns for both cutting and cleanup.
