A swordfish that reacts quickly to falling baits. The metal jig is very effective as a fishing method that makes the most of its habits. However, lead has a fast fall due to its characteristics, and even if it is made into a shape that causes it to fall slowly, it will pass through the range of the swordfish in no time. Therefore, we used zinc, which has a low specific gravity, for the sword jig. Based on water, lead has a specific gravity of 11 and zinc has a light weight of 7. By taking advantage of this lightness, it is possible to increase the appeal and to increase the bite rate by slowly falling the range where the swordfish is located. Since the swordfish are sensitive to light-emitting objects, the color lineup is centered around the glow system and incorporates zebra systems with high glow and flicker effect. Wire assist is standard equipment to prevent line breaks that are inherent in fangs. A sword jig with no blind spots when attacking swordfish was completed.
