I'm one of those people who has just never gotten the hang of removing perch eyes using my thumbnail. The eyes inevitably rupture and are then next to worthless as bait. So this week I set about trying to figure out an easy tool for perfect perch eye removal. The answer was as close as the extra potato peeler I bought by accident a few weeks ago
With a little modification, the pointed end works great. To make it work, I sharpened the edge all the way around that point with a file. The result is something like a mini melon baller. Then I flattened the point just a bit with pliers. Finally I pinched the shaft up next to the handle so it doesn't rotate much during use.
To remove an eye, just plunge the sharpened point in next to the eye, twist the tool to sever the membrane all the way around, then push it in under the eyeball severing the nerves and remaining connective tissue.
Lift the eyeball out and your perfectly prepared bait is ready to tip your jig. I used it today and it performed flawlessly.
