Anybody ever think of building an aluminum mold of a bulk bought balsa lure body and tooling in the mold the gills, mouth, scale pattern and eye placement. When  you screw the mold together it places the imprint cut into the lure of the baitfish features? Think it would work? :-?

seems like it would be a lot more expensive than carving in the details yourself

It's a cool idea but I've never understood why all the extra work carving those details on a crank.   Good for catching fishermen I guess.
