Bozles TG Nobunaga Neo 200g Tungsten Slow Jigs
The TG Nobunaga is a typical knife jig but since it is made of tungsten they can make it a whole lot thinner and smaller than an equivalent lead jig. These things drop quick and have a ton of action when jigged on the retrieve, perfect for yellowtail and bluefin fishing as well as any of your bottom fish species. In current and depth these will behave like a 300-350g jig because of the smaller overall shape, but will save you on the fatigue of using those bigger sizes.
These are 7oz jigs with a thickness of only 1/4" - 3/8" and a bit over 7" in length. Due to the longer profile they have a lot more action when slow jigged and can handle more depth than any other jig with the equivalent length.
