Hmm, just looking at my tiny selection of dip pens I notice that the Hunt 101, 22 and 56 look very similar in size to the Zebra. Although I cannot see the pen it does look like these nibs may at least fit. So, continuing this line of inquiry, is the feed nib interface so exact that it only works with the Zebra?
I confess I do not understand any of the physics involved in this but I would have thought that a fountain pen that could fit several types of nib would be quite desirable. Just wondering now if the difference between the Nemosine nib and the Zebra is the same as between, say, a Hunt 101 and the Zebra - in terms of physical size that is.
One other consideration. How critical is ink selection going to be here, given that this is a dip nib?
These are good questions.
Oh, my pen can accommodate several types of nibs–the ones I've tested it with. Those are the only ones I can guarantee.
For the record, there's already a pen on the market that was designed so you could tinker with multiple dip nibs, and it even has a stainless steel flex nib as one of them.
The geometric differences between the nibs around which I designed my pen, and the nibs you mentioned are enough to turn an otherwise pleasant, reliable pen into a nightmare. Trust me, I put in the hours.
I would have loved to create the One Pen to Rule Them All, but that was simply a physical impossibility. Just like different pastas are made for different sauces, no one pen can hold every type of nib–well.
You can use regular fountain pen ink without issue. I have tried india inks, and though they worked great for a few minutes, they clogged the feed just like I expected them to.
p.s. I just added these to my FAQ.
