You need to be careful using anything with an edge on it inside the hook eye. I learned this by accident, I nicked the inside of a hook on a flipping jig using a 1/16" drill bit on my Dremel to clean the eye out. I didn't notice it but when I went to tie it on I could feel the spot that was nicked and it only took a couple strokes back and forth for it to cut the line, never did that again. Now I use a small scrap piece of .018" diameter wire and I heat it up and stick it through the paint, and I do this before I cure but when you use a fluid bed you don't get too much paint in the eyes.
