Last week, I posted on Instagram, sharing an interesting situation. The Kawari-Nuri and Nashiji Nuri pen I own from Tamenuri Studio takes Bock #6 nibs. For this particular use of it, I decided to put the new cat-engraved nib from Shibui North into it.
Unfortunately, to my surprise, it didn’t fit! Both nibs are Bock #6, with no sign of damage to the housings. And there started the mystery I have found myself enmeshed in now. Why didn’t both nibs fit? And, when I tried a couple other nibs, why didn’t they fit?
Because I shared this on Instagram, I felt it was worth following up. And, the amount of feedback I received and the research I did means it needs more than an Instagram post to cover everything.
CAVEAT: I am not an expert on Bock nibs, nib housings, or even nibs in general. I’m only sharing information I gathered after posting about an issue I came across last week. I have done my best to not make any hard claims, as I really can’t say what’s going on here.
