[This isn't exactly a technical problem in the usual sense that he handles things, but it's hardly outside of his ability. He sits down and sets to work after studying the materials on hand, picking up a couple of coffee filters and using one of the pointy bits of his tech-bō to make holes in the ends once he folds them over.

This is where the fabric scraps and fishing line come in as he winds the latter around pieces of the former for a makeshift cord, and once he has several of them he ties one end of each around the wire loops on the filters.]
