Well I took a pair of pliers to the most expensive pen I own today. Here's the result...

Has anyone else tried this? Given that it's a clear pen, it's not that much of a challenge as you can see which bits are threaded and unscrew. The bit I came stuck with is the cap - has anyone managed to disassemble the cap?

Wow, that takes courage! Thanks for posting the great photo - that is a wonderful reference for any of us that need to get in there to fix something.

Please do let us know how the reassembly goes - any challenges that arise!

It's really great that the section unscrews to permit a more thorough flushing - I hope I never have to take things further than that!

Hi,

I think the caps on カスタム pens come apart when you unscrew the top black piece.

Wow. Very cool picture, thanks for sharing.

Could you please pretty please give us a quick guide as to how you did that? I would be very appreciative of that.

Why?

Ah, didn't know the plunger assembly unscrewed! Thanks for sharing this.

Actually, the only time I used the pliers was to remove the plunger bit. When you unscrew the plunger and pull it out, you can see that there are two flat bits on the threaded piece. I just gripped this with my pliers and unscrewed normally.

The nib and feed just pull out - grab them firmly and pull straight out. The section unscrews and is finger tight so you can unscrew this easily. Actually if you unscrew the section a little, it may be easier to pull out the nib and feed.

Finally, there is a black threaded plug that the section screws in to. This is easy to unscrew, also by hand...

Edit: I tried to unscrew the black bit at the end of the cap and it turns but doesn't unscrew. I think it may be a push fit... anyone have any insight?

Siv, why did you want to disassemble your beautiful and expensive pen?

'cause I want to get the metal bits Rhodinated

I got no beef with disassembling beautiful pens- the only truly beautiful pen worth the extra expense is one you can field strip.

Siv, I noticed the same thing on the 823 I bought from you. It's something I've seen on a lot of piston fillers, and how I've taken the piston out them, mostly some vintage Kawecos. Never occured to me to try it on the 823, though I suppose that was beacuse it was on loan originally. "Here, sir, is your pen back... In parts!"
