I’ve gotten the left-handed Z50 nib, for minimalizing confusion and your philosophical comprehension on stationery.
When I’ve introduced myself to fountain pens, and once using them for the first time, the pens gave off a scritchy-scratchy feel and sound. It is official that it has displeased my fingers and eardrums. However, what has baffled me beyond my mental limits is that when my parents have tried them out for the kick of it. The pens appeared to be literally gliding across the paper when they wrote with it. Actually, gliding is an understatement. It actually LEVITATED. As a result, my inconclusive mind perceived that it’s not about you choosing the pen, but the pen choosing you.
After a quick session of some modern technique called Googling, fountain pens were actually designed to be “dragged,” not “pushed.” Since I am a lefty, my motions with them did invoke pushing maneuvers. My parents are righties (more like frighties in my opinion), their motions consisted of pulling actions, perfectly giving me a clear answer. This is where Lamy’s left handed nib comes in.
It looks like a normal Z50 nib, but the manufacturers probably did some kind of work to the tip of the nib. It allows for tons of ink-vomiting control while writing, and it gives a pleasant feel and doesn’t produce the scratching noise. Overall, it is a good upgrade if you are a lefty, and I would definitely buy more for my other Lamy pens!
