Shimano engineers designed the Hybrid Edge round bill to achieve a fast and fish-enticing swimming action with the durability to withstand punishing contact with cover. The wide round bill on the MB-50F Shallow protects the front hook while reeling through cover, while the thick-diameter rear hook will not deform easily when hitting unexpected obstacles and adds durability during tough fights with trophies. The unique one-piece weight within the Macbeth Shallow concentrates the center of gravity and allows the lure to recover quicker after making contact with cover while enticing aggressive reaction bites.
