百利金的EF刮纸好像确实是普遍现象
美国一个很有名的钢笔网站(Richard Binder)卖的EF见都是他自己用F尖重新打磨的
他在网站上给的解释是
We include extra-fine nibs (XF) as a specialty grind because Pelikan’s standard extra-fine nibs (labeled EF) do not meet my quality standards; they are inconsistent in flow, smoothness, and stroke width. If you order an extra-fine nib for your Pelikan pen, I will regrind a standard fine nib to create a smooth, reliable extra-fine writing experience for you.
