This leaf spring is a homemade item that has helped catch many big fish in the past. It's a masterpiece crafted from the leaf springs of a light truck. It has been used to catch a 2.5-meter-long shark, and you can even investigate it using G-force measurements. It has also been used to catch fish like Giant Trevally (GT) over 20kg and Groupers (Mee-bai) weighing 36kg. This leaf spring is an indispensable item for big game fishing in various locations such as Hedo Point in Okinawa, the rocky shores of Higashi Village, and fishing ports. I've sold five sets of these stone-butt leaf springs to my fishing buddies. They are highly praised as an affordable and excellent stone-butt leaf spring set. Big game anglers, please try it out! This leaf spring can be folded in half or disassembled into two parts, and it can be assembled in just 5 minutes. Use this leaf spring to create great memories of big game fishing.
