Strike King Tour Grade Tungsten Weights are insert-free, designed to not fray your line and have an incredibly durable paint coating. The Tungsten Weights' boat-tail/weight forward shape allow the weights to easily penetrate and fall through cover. Tungsten's high-density enables a smaller size than comparable lead weights, which makes them less obtrusive to your lure and will help your hook-up ratio. Plus, the Tungsten Weights' hardness gives you incredible feel of the bottom and strikes that can't be matched by lead.
