You can use that Mustad straight eye hook. I first heat the eye to a cherry red for about 30 - 45 seconds, let it cool a bit and cast my jig (I was using a sparky jig),the using a drill press and a pin punch gradually open the eye as needed. Then it paint, tie, attach blade and close the eye and done. This reduced the broken eye significantly and i don't know of any that broke during use.
