Thanks guys, this has been super helpful. I guess I AM looking to make a perfect jig head, but I was more concerned on the strength so it doesn't come out as soft as a typical weight that is easily dinged and therefore would flake the paint. I do a lot of Crappie fishing and love using the Blakemore Road Runners but wish it came in a different head shape and had layered colors and attaching different blades just ends up costing more money. Figured making my own would satisfy both my want for the type of jig head I am imagining and my curiosity for making custom lures/jig heads/etc, even if it doesn't end up saving me money.
Also, the previous post mentioned copying the Blakemore jig heads. I'd be lying if I said I wasn't intrigued with the idea of eventually selling these jig heads after I got good at making them, so my question is - I love spin jig heads (like Blakemore/Sworming Hornet) but if I created my own style head is that still infringing upon them? My idea is more of a frog shaped head, but not quite as flat (like a bullet with four round corners) with an eyelet on top for line and an eyelet on bottom for the swivel and blade. I would never intentionally sell products that would infringe upon copyrights but IF I get to the point of selling them I'd like to know what's the difference between making something in the same category of those and actually copying them.
