These are a 7/8 oz vertical jig. These jigs tipped with a worm, mimic the shape of a juvenile lamprey. Made with a 4/0 Matzuo black nickle sickle hook. These hooks have an angular bend and are very sharp. Jigs are powder coated then heated to a high temperature, producing a superior extremely durable finish. Each jig comes fitted with a willow leaf style blade secured at the belly.
