I bought the "Black with Gold" option with the Fine nib. It weighs about 27 grams with the cap and 13 grams uncapped or unposted. (As a comparison, my Kaweco AL Sport pen weighs 23 and 14 grams respectively.) It is made of aluminium that is electroplated and covered with some protective coating. It looks gorgeous. At first it was too slippery in my hand, but over a number of days it started to feel alright. It is not yet as comfortable in the hand as my 30 years old, like new Harley-Davidson -- I had two of them and this one I had not used until about a month ago.My previous favorite pens were the above mentioned Harley-Davidson and an equally old Feraud. Both have a medium (or a little wider) nib and slide extremely smoothly on paper. When I want thinner, more precise lines, I turn the pens 180 degrees around and write with the back side of the nib. Both of these pens slide perfectly in this reverse mode. The Fine Schmidt nib of the Scriveiner writes a little thinner than the other two in the reverse mode, slides perfectly on paper and is a pleasure to write with. Even though I have absolutely no need for an even thinner line, I tried to write with the reversed nib, but it gets very scratchy.I find the length of the unposted Scriveiner (11.6 cm) perfect in my hand, just like the Harley-Davidson's 11.4 cm. Both take the 73 mm LONG standard WATERMAN INK CARTRIDGES -- this is a major advantage in my usage and this fact does not seem to be advertised, at least not clearly enough. Of course, one can use the widely available 38 mm standard cartridges in both and the Scriveiner comes with a very well engineered 'converter' included. Feraud and Kaweco are shorter (10 cm each) and they need to be posted for comfortable writing. (Capped, they are all about the same length.)Speaking of ink. I wanted to match the black Scriveiner with the Intense Black ink of Waterman and use the Serenity Blue ink of Waterman in my dark blue Harley-Davidson. Unfortunately, the black ink of Waterman does not flow well in the Fine feather/nib of my Scriveiner. Every now and then I have to press relatively harder on the paper to get the ink flowing again! On a hunch, I swapped the inks around and put the blue cartridge in the Scriveiner. Now it is faultless!!! The added benefit is that the black ink in Harley-Davidson leaves a slightly less wet line on the paper -- just the way I like it.AN UPDATE:About two months later, I bought the "Silver with Gold" option with the Fine nib. This is made of brass, as opposed to the aluminium "Black with Gold". The aluminium and brass pens weigh about 27 and 49 grams with the cap and 13 and 30 grams uncapped or unposted respectively. Interestingly, the "silver" version is less slippery between my fingers than the black version. Otherwise, both have identical dimensions.What I did not know when I wrote the original review is that this pen can carry two (2!) 38 mm standard cartridges simultaneously -- one connected to the ink feeder in the normal position and the other in the reverse direction behind it. I read this in another review by chance. I very much like this feature, because when one cartridge runs empty I simply switch them around immediately and replace the empty cartridge later at a convenient time. None of my other pens accommodates two 38 mm cartridges simultaneously!FURTHER UPDATE:Another 5 months passed and I bought the brass pen with fine nib. Now I have a collection of three pens. I do not like to have my brass pens covered with fake paint decoration and lacquer. I prefer the look and feel of bare polished brass.So, I removed the lacquer with very fine sandpaper and polished the pen with a universal metal polishing paste. The only place I did not touch was the grip section, because polished brass is more slippery than the lacquer of Scriveiner pens. The result is shown in the attached photos in the middle of the chrome and black anodised pens.I found that the Schmidt stainless steel F nib wrote a little too wet for my taste and replaced it with a gold plated EF Schmidt nib. It writes now a little less wet, but I cannot see the line being any thinner. Maybe it is just a little thinner, but not by much. On the positive side, it is not scratchy at all.From the point of view of writing or gripping comfort, my favourite version is now the gold-look-alike polished brass pen, followed closely by the chrome and gold version. The black anodised aluminium pen is still too slippery (and a little too light) for my taste. But this is just a relative assessment within the Scriveiner group. All three are excellent pens.Hopefully the LAST UPDATE:Another 4 months passed and I could not resist buying the copper pen with fine stainless steel nib. I undertand that this too is actually made of brass. I replaced the fine nib with an extra fine gold-plated Schmidt nib assembly that I bought over the internet. It looks luxurious and is a pleasure to write with. I have not removed the lacquer yet, because I ...
