I have a mold, bought from someone on Ebay, that pours 1/32 & 1/16 oz spoons like that, but have not used it much yet. It came with eyes, that were home made from copper wire and I need to get or make forms for it, as the eyes don't pour very well. Unlike a sinker eye, they don't fit the mold very well, and with the spoon so small, I get poorly formed spoons. No one here ice fishes, we don't get ice, but I would think they could be used for jigging as an alternative to regular Crappie jigs.
