Drive Beaver SW is set with a small amount of salt in and semi-hard material assuming the conditions of use at sea and the rig. In order to balance the contradictory conditions of holding the worm's needle and good hooking, we use a semi-hard material that is neither too hard nor too soft. It is required to complete a variety of actions at a high level, such as lift and fall, slipping and staying, and the angler's operability is an essential item. Considering the importance of operational feel and durability, a small amount of salt-in is used. Even with a wide range of rigs from 5g to 30g or more, it does not impair Basaro action and boasts the performance required at sea. The Drive Beaver SW, with its torque-filled and dynamic action full of life, will bring a new twist to the sea hog scene.
