The molds I use to make these are custom made. The guy that I got them from is no longer with us. He lost a long battle with heart disease. He was a GREAT guy and one of the best fishermen I have ever met. They are made from bar stock alum. Like Skip mentioned earlier, I spent the better part of a week down south learning how to make these things. They are a great jig even if I do make them....lol. Good Fishin'....GF
