What is a ten-centimeter slender needle eye with a tail end?

A ten-centimeter thin needle with a needle eye at the end is used for fishing. In the fishing field, some fishermen have some related applications to sewing needles (including traditional sewing needles without side openings and emerging sewing needles with side openings). When using a small hook (e.g. 0. 1, 0.5), use a slightly larger sewing needle (e.g. 10cm long, optional for side opening) to go fishing, hang the hook in the pinhole at the needle end, and the earthworm can be easily inserted into the hook through the sewing needle. Compared with the traditional method of hanging earthworms, this traditional method of hanging earthworms is difficult to hang earthworms on the thread tying place and the hook handle (hanging here means that the thread tying place and the hook handle are completely hidden by earthworms). This method of hanging insects by sewing needles can solve this problem. Both the traditional sewing needle without side opening and the new sewing needle with side opening are designed to bring the sewing thread into the pinhole, so the pinhole is designed to be small, and small hooks can be hung in, but slightly larger hooks can't.
