Fishing Type/Fish Species: Squid/Eging Type: Fishing Hooks/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 works in deep water as well. 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~L (Katsuichi, Owner Outbarb, etc.) Number of hooks: 1st hook x 2, 2nd hook x 4 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 spring-loaded, so it enters the water without bouncing when deployed, 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 (1st eye), naturally causing it to flip up, hooking 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 detail. ④ The shaft may bend if a squid is hooked, so please correct it before the next use. Thank you. @Origin Kobo aolijinn
