Hey Aaron: I was trying to reset a nib in a standard early doric, the kind with the Eversharp screw out inner section (like the current interchangeable Pelikan nib system).
However, the nib got hung up and when I looked, there seemed to be a nib shaped slot cut in the top of the inner section. have you ever seen anything like that ? I got the feed out with my knock out block but the nib is so tight I actually broke a tine trying to wiggle it out with my nib pliers! And its still in there.
I know I have bad hands but haven't broken a nib in about a decade, so wondering if there's some special trick with these sections.

Those nibs and sections can be tricky.  First off, I would advise against using pliers to pull the nib unless they are coated with rubber or plastic.  For something like this I use my fingers but a rubber jar opener will serve you well.  It protects the iridium and gives you something to grip.  The inner section part is hard rubber, so apply some heat with a hair dryer for a few seconds and the nib should wiggle out nicely.  For re-tipping check out Greg Minuskin or John Motishaw.
