The ball bearing snap swivels not only allow the blades to spin freely, but provide the versatility to the angler to change blade sizes and colors. The Bomb sports double #8 fluted blades on a.051 shaft. The top blade is held in place with a semi-wrap on the end to prevent swivel loss. Two 7/0 hooks produce consistently solid hook-ups. Additionally to the blade thump and tick, a magnum trailer grub is added, providing not only a visual aid, but more vibration. Utilize a straight retrieve, helicopter it down a weed edge, or rip and pause over deep water. No matter how it is presented, the blades are always working for you.
