Fishing Type/Fish Species: Squid/Eging (Squid Fishing with Eging Lures) 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 1st hook to the 1st eye (assuming a 18cm horse mackerel), approximately 13cm from the 1st eye to the 2nd eye, total length approximately 33cm. ③ Hook size: M to L (Katsuichi, Owner Outbarb, etc.) Hook count: 1st hook x 2, 2nd hook x 4 ④ Roller: Φ10mm custom-made (Material: POM) Self-lubricating type ⑤ Uses a 3.5g sinker for weight. ⑥ Started selling on Mercari because I want yaen anglers to use it. Has 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 deployed, preventing line tangles. ② When the yaen reaches the squid and the reeling action begins, the tail of the horse mackerel hits the lifting eye (1st eye), naturally causing it to flip up, hooking the squid. (See Figure 5) ③ Used from autumn juvenile 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 or are overly concerned with minor details. ④ The shaft may bend when a squid is hooked; please correct it before the next use. Thank you. @Origin Kobo aolijinn
