A wellbore fishing tool (1) configured for engaging and retrieving a fish in a subterranean well, comprising an actuation motor (5) and an actuation member (23) operated in an axial direction by the actuation motor. It further comprises an engagement assembly (10), wherein the engagement assembly (10) has a main body (17), gripping elements (13) configured to be moved between a non-engaged and an engaged state, and said actuation member (23) between the actuator motor (5) and the gripping elements (13). The gripping elements (13) connect to the actuation member (23) via a connection hinge (29).
A wellbore tool (1) comprising an inner bore (17a), an axially forward-facing aperture (32) constituting an access between the exterior of the wellbore tool (1) and at least a part of the inner bore (17a). The wellbore tool (1) further comprises a debris plug (20, 120) in the forward-facing aperture (32) when in a barrier state, and a plug retaining means (9) configured to retain the debris plug (20, 120) in the forward-facing aperture (32) and to release the debris plug.
