[edit] koh-i-noor?

did koh-i-noor make rapidographs, or did they import rotrings from germany? -- Akb4 05:56, 31 August 2006 (UTC)

[edit] KOH-I-NOOR and Rotring both use the name rapidograph, are they related brands?

KOH-I-NOOR (Chartpak) rapidographs are of different construction than Rotring's. The construction is more complicated and seem to use better materials; furthermore, the nibs are replaceable where as Rotring's are not. Based on the following page KOH-I-NOOR rapidograph are manufactured in the USA: http://www.chartpak.com/kohinoor/select_rapidpen.htm. I've owned both. The opinions on performance between the two is non-conclusive. Personally, I seemed to have leakage problems with the Rotring's, but I've heard the converse as well.

What's confusing is that KOH-I-NOOR and Rotring products are often shown together on the Chartpak site, but that might be due to Chartpak acquiring parts of Rotring?. – Zhaoshouren (talk) 06:42, 20 May 2008 (UTC)
