It is a _very_ handsome pen. Here's a question: why doesn't Brian seal the section & provide the converter--give a buyer both options? (Apparently Edison doesn't do that according to the website.) Would it make the converter (or cartridge) not work? How could it do that (prevent the converter) and still function as an eyedropper?
The bottom line with this is that I have a style of section that I make that is easily repeatable for me, and I don't want to alter it yet.
These pens absolutely CAN be used as either an eyedropper or an CC in the same pen (my daily user is like this and I've sold a few like this).
But here's the rub...when I make these sections, I use 26 TPI threads. These are not the ideal TPI for threads that will seal up a section and be ink-proof. Something in the 40's would be better, and with an O Ring.
However, if you maintain the pen properly, and use silicon grease every time that you fill the pen, then there's no problem. At least there's no problems that I've found yet. Keep in mind that these pens are still only about 8 weeks past prototype, and 2 weeks past production!
BUT - Do I want to have 75 of these pens out there sold when I start having people send me emails saying that they just ruined a $500 dollar suit with my pen? My first reaction would be that they did not properly maintain the pen with silicon grease. But how can I give good customer service and basically "accuse" someone of ruining their own suit??
So I could sell the pens with the disclaimer that I can't guarantee against leaks if grease is not used, but I think that makes the product seem unreliable.
So I made a decision that the customer needs to decide between an eyedropper or a CC.
So an eyedropper gets the section sealed with epoxy. Then the pen gets filled by removing the nib housing assembly. The threads that seal up this assembly are 44 TPI, remove with about 10 complete rotations, and will not leak with or without grease.
Now - am I willing to sell the pens where the customer can use both? Yeah, sure...but I won't guarantee against leaks, and you'll need to use silicon grease every time you fill the pen.
If you want this option, and later find that you want the pen sealed up, I can do that.
