Probably my OCD kicking in, but if they made a #3 sickle hook, they could just throw all the rest of them away lol.
#4 always seems a hair small, and #2 a hair big to me. Does anyone make a #3? Also the only ones i have had experience with are the Matzuo ones, are the Eagle Claw little nasty's the same size?

My solution is to use the #4, but bend the gap open just a bit. Still wishing for a #3 though.
