A fishing tool for fishing sucker rods from a subterranean well. A body of the tool is a machined top piece, a machined barrel piece and normally a machined bottom piece that all thread together. The bottom piece preferably retains a curved cast metal slip movable within grooves milled internally into the body. The slip moves upward to admit a rod into the tool and moves downward to capturing the rod in the tool. A lower end of a side opening provided in the barrel piece is level with an upper shoulder of the slip when the slip is at its lowest position so that the rod engages and is retained by both in the tool. The upper shoulder of the slip can optionally be provided with teeth. The bottom piece can be replaced with a bell and the top piece 16 can be replaced by a prior art fishing tool.
