For Bladed Jigs: On my molds with the vertical eye orientation I cut the hook flush to the body at the bottom and connect the blade. I think close the eye of the hook back up with pliers. I have never had a hook open back up or a blade come out. If the super tiny slit on the hook bothers you you can coat a little Devcon 2 Ton epoxy on it (I stopped doing it because I have not had any issues since the blade runs at the top of the hook and it takes a LOT of pressure to open the hook eye up!).
