Fishing Type/Fish Species: Squid/Eging Type: Fishing Hook/Hook Thank you for viewing. ① The primary design concept is a light overall weight (around 7g). Effective in shallow areas, seaweed beds, and areas with submerged rocks. Of course, it's also suitable for deeper waters. ② Yaen shaft diameter: Φ0.8mm, approximately 20cm from the first hook to the first eye (assuming a 18cm horse mackerel), approximately 13cm from the first eye to the second eye, total length approximately 33cm. ③ Hook size: M to L (Katsuichi, Owner Outbarb, etc.) Hook count: 2 first hooks, 4 second hooks ④ Roller: Φ8mm custom-made (material: POM) self-lubricating type ⑤ Uses a 3.5g sinker for weight. ⑥ I started selling on Mercari because I want all Yaen anglers to use it. I have over 15 years of experience. (Function) ① As the name "Yaen" suggests, it's a spring-type, so it enters the water without bouncing when the Yaen is set and cast, preventing line tangles. ② When the Yaen reaches the squid and the reeling-in action begins, the tail of the horse mackerel hits the lifting eye (first eye), naturally causing it to flip up, and the hook catches the squid. (See Figure 5) ③ Used from autumn squid to spring monsters. ④ The Yaen's balance is maintained by the roller section, providing excellent smoothness. (Notes) ① Due to being handmade, there may be variations in dimensions and weight. ② My Yaen does not use a Yaen stopper. ③ Please refrain from purchasing if you are seeking perfection or are overly concerned with minor details. ④ If the shaft bends when a squid is hooked, please correct it before the next use. Thank you. @Origin Kobo aolijinn
