Thanks for the replys . I used to buy them back in the mid 1970’s. They were true 3-way ball bearing swivels. Identical to the brass one in Blue Fleck’s post,except they were stainless steel/ball bearing. Expensive even then. I was recently on pool 13 of the Mississippi River with my nephew and he asked me if I knew where to buy them.I hadn’t thought about them in a long time since I don’t fish for walleyes much. Those swivels were really nice. Absolutely no twist.
