Fishing Type/Fish Species: Squid/Eging Type: Fishing Hooks 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~L (Katsuichi, Owner Outbarb, etc.) Number of hooks: 4 for the first hook, 4 for the second hook ④ Roller: Φ8mm custom-made (material: POM) self-lubricating type ⑤ Uses a 3.5g sinker for weight. ⑥ I've started selling on Mercari because I want 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 After the yaen reaches the squid and the reeling action begins, the tail of the horse mackerel hits the lifting eye (first eye), naturally causing it to flip up, hooking the squid. (See Figure 5) ③ Used from autumn squid to spring monsters. ④ The balance of the yaen 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 in the product 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
