Self-acting PE line of assist hook. Uses a blue-collar worker that is least wary of fish. The PE line (Dyneema) does not deteriorate in strength due to ultraviolet rays like aramid fibers such as Kepler. Take out the core and use PE woven into a tube. It is possible to create a chichi ring using a needle. If it is the same thickness as Kep1er, it is soft and supple.
