The TICT Aji-Shime Pick (Aji Shime Pick) is a specialized tool designed for quickly performing "brain spiking" (nerve spiking) and "blood draining" on small fish like horse mackerel immediately after they are caught. It is used to prevent the fish from thrashing, preserving freshness and flavor, allowing you to bring home delicious fish. It's compact for storage and convenient to carry, and after use, you wipe off the dirty parts and store it. Main Features and Effects: Brain Spiking/Blood Draining: The tip of the pick is used to pierce the fish's brain (from the space between the eyes towards the lateral line) to stop the nerves, and the gills are cut to damage the arteries, allowing for quick blood draining. Freshness Preservation: Spiking prevents the fish from thrashing, preserving the freshness of the flesh and preventing the reduction of flavor components (such as inosinic acid). Portability: The pick part can be stored with a screw mechanism, making it compact and safe to carry (approximately 5.5cm when stored). Hygienic: Because the fish doesn't thrash, the cooler box and tools are less likely to get dirty. Target Fish: Suitable for small fish caught in light games, such as horse mackerel, rockfish, and barracuda. How to Use (for Horse Mackerel): Secure the caught horse mackerel with fish scissors, etc., to keep it from moving. Place the tip of the pick between the eyes (the space between the eyes) and pierce the brain along the lateral line. Use the small blade of the pick to cut the blood vessels at the base of the gills (near the spine) and drain the blood. By using this tool, you can enjoy freshly caught horse mackerel even more deliciously.
