Abstract
A fishing tool is provided to enable retrieval of a fish from a mineral extraction system. The downhole fishing tool includes a frustoconical member for guiding broken fish such as a broken pipe into a channel created by a sliding car and an edge of a body of the downhole fishing tool. The channel enlarges by sliding the sliding car along the body of the downhole fishing tool. The downhole fishing tool body and sliding car are aligned such that the sliding car slides diagonally across the body of the downhole fishing tool thus creating a larger channel at a first point along the diagonal than at a second point along the diagonal.
