Go-devil

Go-devil are used in wireline fishing operations when wireline is required to be cut. Go-devil is constructed of a solid length of bar with a slot and guide plate through which the wireline is passed.
The tool is then dropped downhole in the conventional manner. Go-devils looks similar to Wireline Stem and has a longitudinal slot on body with a metallic strip pinned within slot, to prevent wireline from coming out.
There are Flat Bottom and Angled Bottom for selective.

Other sizes are available on request.
