Jigging World Diamond Jigs are made with their own Zblade Open Si-wash hooks. These center weighted diamond jigs are one of the most versatile jigs in today’s market. Striped Bass, Black Sea Bass, Grouper, Tuna, and other bottom fish fall victim to this staple jig that’s been around for quite some time. All jigs are chrome dipped in either Gold or Silver to give that ultimate attraction to catch big fish over and over.
