I think the answer is as stated above, the surface of the eye. You need to take a close look, under a microscope if possible or a magnifying glass and compare with a shop bought jig or an out of the box hook.
I first cleaned my eyes with a dremel bit, but I did notice the surface finish of the hook was BADLY damaged, so now I am much more careful and after reading this thread, even more careful.
Many use a piece of wire in a dremel. This should work fine as the wire wall is smooth. If anything, this will polish the eye and improve the line attachment. But if the end of the wire rattles against the eye surface, damage will result. I am going to experiment with a tooth pick in a dremel. The idea is that the friction heat will soften up the epoxy and facilitate the removal. It will be several weeks, so feel free to try it. The important thing is not to disturb the seal to the body.
The trick here is to use a hemostat clamp (surgical type) i have sevral in three sizes 4'',6'', & 8'' ones the 4'' ones work well for holding the eye of you jig while you dip n swish in the FB
you could possably get away with long nose pliers to do this job aswell but i like the hemos as you can lock them into place
what type of rod/line set are you using on the 3 rigs you have?? the reason i ask, a guy that buys alot of jigs from me sort of complained of the same thing.. then i found out he was trying to use 6lb florocarbon with a med-heavy casting rod... i asked him to tie the line to a fence post or something and see if he could break it in the yard (jig or no jig)... well, he found out he needed a little heavier line.. or a lighter rod..
8lbs fluro on spinning tackle(3/16thoz),last year no problem this year (new jigs) problem.....switched to 12 lb fluro on baitcaster(1/4 oz) ...problem (both w/ stand up jigs, 10 break offs) then went to 14 lb mono on bait casting and arkie jig(up to 1/2 oz). Last year no problem, this year at least 2 breaks............12+ breaks in 3 tournaments. I think Im gonna run braided line through all my jig heads to polish out the paint............its just that I didnt have this trouble last year (my 1st year at making jigs).
Could it also be that now since you make your own jigs you don't worry about buying more, or finding more in that color, so you are more apt to throw them in places that you wouldn't before? I know that happened to me when I first started making jigs. Also, just because you went out and bought a spool of line from the store does not necessarily mean that it's "new". I have had trouble with specific lot numbers of line in the past and had to go to a different store for the same line to get a different lot number.
