"cuz we always made them that way! Don't give some hook companies any ideas so they have a reason to raise prices again.
Seriously, I know someone does or used to make a larger "eyed" hook. Some other Ideas; 1) I read (about tying panfish flies) was to tie a normal length fly body on a longer shank hook leaving the front section bare to enable releasing panfish easier. I think this might be a help in tying on tippet (crowding the hook eye when tying). 2)Lefty K. suggests cutting tippet on an angle with a point to faciltate getting through the eye. 3) "Dollar Type" stores carry cheap reading glasses, I've got them stashed all over my house.
