If there's been one lure that has changed the face of fishing over the years, it's the Yamamoto "Senko". With its wide range of uses and subtle natural action, the Yamamoto Senko has quickly become a favorite with anglers all over the world. The beauty of the Senko is in it's simplicity. The Yamamoto Senko may just look like a thick round plastic worm but the fall rate created from the large amount of salt impregnated in the body drives fish mad.
