Flat spot on eyes of Matzuo sickle jig hooks
I ordered various panfish-size jigs off e-bay poured on Matzuo sickle hooks, which I haven't used before. I like everything about the hooks except that they all have a flat spot on the top of the eye. A few of them have a slight ridge of metal on one end of the flat spot.
I see the flat spot as posing a potential problem when fishing a jig below a float, because I think it could make it hard to keep a knot skewed toward the hook point instead of in line with the stem of the eye. (Such positioning of the knot is often needed to make a jig hang level.) Also, some of the ridges look sharp enough to need filing them down to keep them from damaging 2 or 4 lb. line.
At first, I thought the flat spots might be a side effect of some way the jig-pourer was handling the hook, but the same thing was evident in jigs ordered from a second source. The flat spot is there on both bronze and red hooks.
In the close-up photo of his successful woven jig (congrats!), skiptomylu shows a sickle hook that has no flat spot. It looks like a black nickel hook.
What have you folks who use sickle-hook jigs experienced? Do yours have a flat spot on the eye, and has it affected your knot positioning when hanging the jig below a bobber? Are the black nickel versions less likely to have the flat spot?
