Shimano Butterfly Flat-Side Jigging Spoon - The Shimano Butterfly Flat-Side Jigging Spoon is one of the original jigs that helped pioneer speed jigging in the United States. This jig is designed to be fished vertically or angled while drifting, and the unique rear/center weight balance design causes the jig to fall to the bottom quickly to mimic an injured baitfish. Anglers need to fish this jig with a rapid yo-yo style jigging technique.
