I recently ordered a custom grind from Deb Kinney. I sent her my Omas Paragon with B nib and asked her to transform this into a medium stub.
Well, yesterday I got my pen back, about a week after I had sent it to her. The nib was rather boring and dull before I sent it in. Now it is absolutely fantastic. Great line variation coupled with the highest ease of use. There is no roughness to this nib. It catches at all times. And my handwriting looks very nice to me. This nib has great character and writes almost like an italic nib with none of the roughness that they come with usually.
I am absolutely thrilled by this nib and will try to post some images of the pen (it's the nice saffron blue color), the nib and a writing sample soon.
