CONE

would also describe the cone, although the cone might encompass more of the top of the pen than only the end. So technical!

Yes, amarpaul, that Cartier pen you found does have a similar barrel's end to what the asker is describing. Over $7,000 for a pen! Yikes!

Good catch about the cone.

I am quite surprised at being unable to identify the pen, given that I obsessively pore over Mont Blanc's Limited Edition catalog in the forlorn hope of someday being able to afford one.

I think it's a Cartier, maybe one like this: [http://www.amazon.com/Cartier-Dragon-Limited-Fountain-Pen/dp...] as it has a "Mother-of-Pearl cabochon is set into the barrel's end" (barrel's end being the "cone")

Voila!

The asker is most probably referring to a Montblanc pen, as her previous question referred to Roger Moenks' photos of actresses holding Montblanc pens.

Montblanc instructions refer to the cone and show the top of the pen.

It's marketing copy, Joshua - they'll say anything!

Also, the barrel cap (the "blind cap" in your second reference) looks conical (more like a frustum actually), and the shape may vary from pen to pen. And it is functional in many pens (serving as part of the filler mechanism).

Also, pen manufacturers come up with wierd embellishments, eg. [http://www.montblanc.com/72.php?showSubKat=true]

b.t.w. thanks for the reference ... I really fancy fountain pens. :-)

The caps of some Mont Blancs are clear and shaped something like a rounded cone, and have a diamond embedded in them ...

Similarly, observe the shape of the end of the pen barrel in this picture [http://www.c2coffer.com/data/pic/20110731/source_img/_S_1312...]. That looks conical too.

I suggest you try to Google the brand name of your pen and see if you can find a picture of it.
