Know what model(s) you want? You’re ready for nibs:
Once you’ve determined which model(s) you like, now comes the fun part: picking out the nib.
Nib Material
F-C nibs are available in High Performance Steel (HPS) nibs as well as 14kt gold nibs, which are plated in rhodium for a silver color. Prices for all pens include a standard HPS nib in the regular sizes EF-1.4 or 1.5 (there is an additional charge for the #6 steel EF Flex, 1.9 music as well as 14kt gold nibs).
Nib Color
For some of the steel #6 nibs, you have the option of getting a polished silver or black nib at no extra charge. Black nibs are not available for #5 nibs, 14kt gold nibs of any type, or the steel EF Flex.
Nib Grind
F-C sets and tunes every nib, whether it is a stock nib or their in-house SIG grind (more in a bit) or nibs from Yukio Nagahara (and previously Mike Masuyama). What this means is that they get their nibs, feeds and housings all separate, then they put them together into the nib housing. After that, they check and tune the nib to make sure the tines are aligned, that ink flows well and the nib writes as expected. Then they clean the nib and install it into the pen. Every nib goes through this process, so even a non-ground nib should have a great writing experience (my favorite of their stock nibs is Medium in both #5 and #6).
If you want to get something different, which I highly recommend, consider getting one of the nibs from Yukio Nagahara, who was formerly a nib grinder for Sailor in Japan. For an additional $25, you can get a Needlepoint, Fine/Medium/Broad Cursive Italic or Medium/Broad Stub. Due to limited quantities, Nagahara nibs are only available with the purchase of a pen.
F-C’s in-house SIG grind is another great option. SIG stands for Stub Italic Gradient and was originally developed by the late Jim Rouse. It gives you the writing experience of a stub with the line variation closer to a cursive italic. Unlike Nagahara nibs, SIGs can be purchased separately, which makes them an affordable way to swap out different grinds between pens.
I recommend checking out F-C’s Nib Details page which has a lot more information about the nibs, materials and grinds.
