I guess I was thinking they made a mold like the standard walleye jig mold.
Could you please post a picture?
I have a mold called the walleye jig mold or so it says on the side of the mold cast in the aluminum.
The mold is made by Do-it but it's cheaper to buy from vendors such as Barlow's tackle.
There are hundreds of molds available out there for most anything you could want.
Do-it molds run ~$35 each.
There are others but Do-it makes a decent mold at a reasonable price and has the best selection.
Plus there American made!
