The last couple of days I've been testing my Japanese nibs to get an understanding of why there is such a difference between the fines and mediums before deciding on my next purchase. What I really want is a nib that is smooth but won't lay down ink that feathers or has outlines that are too soft looking. So I put mine to the test and discovered that the key to getting the nib I want has less to do with the nib and more to do with how I wield it.
"Huh?" I can just hear the collective FPN voice. "Say what?" Here's the deal. When I use no effort and let the pen do the work, all of my Japanese nibs are smooth writing. When I put a little pressure on the nib, most act scratchy, the wider nibs less so. In fact the Pilot Prera can take a decent amount of pressure on its stainless though tipped medium nib without a hint of trouble. But it's so much nicer to use it gently and be able to write longer with less hand strain.
Well, I heard a couple of "Duh!" type remarks from the more experienced amongst us and a few

from some newbies. Certainly backing off on the pressure (a holdover from using ballpoints, roller balls, gel pens and the ubiquitous pencil) won't cure tine alignment or other nib problems. But if you've examined a scratchy nib under a loupe and see nothing amiss, try resting the pen in your grip not gripping the pen in your hand. You may just have a gem and not know it.
