Hello, this is Eureka admin (The fountain pen researcher)
so far, especially for non-urushi fountain pens, only bock M nib were available.
I avoided finer nibs such as EF / F, because I trusted M nib quality the most.
because of this, other nib sizes were not available for purchase.
however, recently I did some nib grind for some customers.
Bock M nib is turned into different nib sizes, by nib grinding.
so far I did the following sizes:
1. EF
2. vertical line EF / horizontal line M (narrow vertical stroke)
3. M (stub)
4. F (stub)
* All sizes do not scratch, even the EF.
* I try my best to make the nib smoothest possible with minimum baby-bottom, so as to prevent skipping.
so far, these are the grinds I did recently (although some other special nibs vaguely come to my mind).
If you can suggest other nib grinds along with pictures, I can assess whether I can do it or not.
The nib grinding process requires considerable amount of effort, precision, and time (about 30min ~ 1 hour), to make sure it is of superb nib grind quality.
After grinding the shape of the nib, nib smoothing process is necessary.
The nib grind service cost will be $20~$25.
The price of the service can vary a bit, depending on the difficulty.
Below are examples of nib grinds
(I will continue to add more example photos.)
1. vertical EF / horizontal M (narrow vertical stroke)
thickness approx 0.3 / 0.7mm
2. EF (Both verical & horizontal)
thickness approx. 0.3mm
*Because the EF is grinded from M, the nib point is longer than a typical EF nib point (which uses smaller nib point).
3. M Stub (Vertical M, Horizontal EEF~F / the faster you move, the thinner horizontal line gets)
thickness approx. ~0.7 / 0.1~0.3mm+
4. F Stub (Vertical F, Horizontal EEF~F / the faster you move, the thinner horizontal line gets)
thickness approx. 0.4+ / 0.1~0.3mm+
