Wing Sung 601 - Review

[WJM]

Or you can get replacement nibs. You can find standard fines or even modified upturned nibs which write more like a medium. If Wing Sung nibs don't do it for you, Jinhao 911/51A/85/86 nibs fit Wing Sung 601 and in my experience they're smoother than Wing Sung nibs. One of 601s has a nib taken from Jinhao 86 because the nib was too good to stay in a pen I don't use.

I believe the gold cap 601s are more generally available in China, which is why you can get the individual caps from 3rd party sellers online. They have a variety of interesting textures / patterns / scrolling (not sure what the technical word for it is). 

 

(Nice collection, BTW. I, too, have a Jinhao nib in one of my WS601s; mine came from a $3 Jinhao 911, I think, and is one of my best nibs. Sometimes you just get lucky.)
