This is my homemade single roller Yaen R-type. Stainless steel rod: 1.0mm (0.8mm for roller axle only) Hooks: Out-barb M size, 4 hooks x 3 locations Weight: 0.8 gou (movable) Length: Approximately 32.5cm Weight: Approximately 11g The stainless steel resistance blade is designed to press the hooks against the squid when they are set. The center support has a roller, and the rear support has a Teflon tube. The joints are reinforced with copper wire and soldered. Since these are handmade, there may be slight variations in the position of the hooks, blade, and roller, as well as the length and weight. Please understand. For additional orders, we offer a 100 yen discount for each additional piece. Mixing with other types is also OK. We will create a dedicated listing if you leave a comment.
