The ONIMARU is a metal blade whose design is based on a special balance based on research into the behavior of marine predators.
By clearly highlighting the ley lines on the body of a fleeing sardine, ONIMARU emphasizes the "prey" element that is most likely to be hunted, including sea bass, which have excellent line vision. Its horizontal swimming position faithfully mimics the silhouette of a small fish on the run by emitting high frequency vibrations at any recovery speed without stalling.
The advantage of the hook being mounted on a rolling swivel is that it greatly reduces the risk of breakage or unhooking by limiting twisting and the fish leaning on the lure during the fight. Its general design also greatly reduces the risk of tangling between the hook and the leader.
