It features a twin-body structure that allows for use of only the second body by cutting it at the connecting point. A head is provided on both the first and second bodies to make it easier to lightly hook the trout. The most distinctive feature, the flat tail, has been thinned to the extreme to improve responsiveness. It can produce a seductive action with rod work, and it sways spontaneously even in slight water currents, enticing bass to bite.
