Under my 10x loupe, I can see that one side is ever so slightly out of alignment with the other, causing scratchiness in one direction. This is an infinitesimally small delta, and I had to look very closely with the loupe looking at both sides of the tip to see the slight catch/edge that was pulling up fibers from the paper.
I did some bendy exercises on the nib, which I saw helped improve the problem by about 33%. I am basically taking my fingernail under the tine that is too low and lifting it up gently repetitively.
There is so little iridium it seems on this EF nib that I am very much afraid to use micromesh.
Is that a safe assumption not to ever use micromesh on this?
