This is a fishing rig for ayu (sweetfish). It is a set of 9 rigs, tied in 3 stages with W butterfly hooks and柳 or 矢嶋 size 8 hooks. It can be used for friend fishing, ayu lures, and ayu ing. Compared to anchor hooks, butterfly hooks have fewer snags, and even when the ayu's scales harden and they start kicking the hooks, the sharp points firmly embed themselves in the fish, allowing for quick lure changes. Unlike aチラシ rig, this rig doubles the coverage area, making it a rig that allows you to catch and hold ayu faster thanチラシ hooks. By tying them in 3 stages, the reach of the hooks is extended, making it effective for playful ayu and schooling ayu.
