Honestly you don’t need a throughwire construction, at least for bass fishing. Buy 1 1/2 inch zinc cotter pins from Home Depot, drill a hole so they fit snugly inside and rough up the outside of the cotter pin surface with a file. Glue with Gorilla Glue (the waterproof, expanding type, I forget what it’s named exactly).
I sometime use as little as half and inch of the cotter pin inside and it is solid. If you use a full 1 1/2 inch pin with plenty of glue you will break 80lb braid and bend out 4x hooks before that pin pulls out!!!
