If you're gonna knock Conid for using Bock nibs, you have to equally discredit Hakase for using Sailor/Pilot nibs found on pens that are 200 bucks. Or Nakaya for using nibs found on the Platinum 3776 (which is around 150-200). As for offering much more, that's highly subjective. Although the materials you mention may have more value to some, I would hardly call it universal. I actually find a lot of the Hakase pens I've seen quite ugly. Not to mention they don't have the bulkfiller system-I believe they're typically converter cartridge?
Nibs - how many pen use pilot nibs outside of pilot and Hakase? Probably none. How many pens use bock nibs outside of Conid, too many to count.
Filling system - cartridge Convertor, yes, Hakase uses that. Hard to use anything other than that with natural materials. Would you be able to incorporate a piston filler with wood? Or tortoiseshell and buffalo horn?
As for the bulkfiller, main USP is the ink capacity and perhaps the reliability. If I want ink capacity, several Japanese eyedroppers hold more ink. With the shut-off valve, they dont leak either.
My point with the posts above is: you are machining literally everything, and yet not delivering the product on time, with little communication on delays. On the other hand, another maker is hand turning everything (except nib, outsourced), no other employees to work with, and yet manages to deliver in time, with outstanding communication to boot.
And no, side gig is not an excuse. You may start a part time work, but with clients the expectations will remain the same as that from someone fully engaged in it. Great product, communication and timely delivery.
As for myself, my previous order was 12 days overdue with no communication. I had to email to ask what is the status and why it hasnt been shipped. From what I can make out from the replies, things were worse now.
