The Luhr-Jensen 1/4 oz. Shyster In-Line Spinner features a built-in swivel that virtually eliminates line twist and an instant-spin blade design for instantaneous blade start-up on the retrieve. This spinnerbait can be fished straight upstream, crosscurrent and downstream in rivers. The thick blades provide a strong vibration and are not likely to incur damage if bounced off a river rock or hammered by a large fish.
