After viewing some older posts about some of the products made by the U.S. company, Karas Kustoms, I was stimulated to check out the KK website, and I just received two of their fountain pens. I went with their "Signature Series," and within that series two of the "Decograph" models.
Here are photos I took yesterday of the two pens. Each pen comes inside a very solid stainless steel ("SS") cylinder that twists off in the middle. The Karas symbol 'K' is on the upper part of the cylinder. After removing the upper part, the pen is revealed, sitting safely in a foam insert along with KK's "cheeky" instruction sheet (read it) rolled up inside. I've unrolled it for the second photo.
Here are photos of the Signature Series "Black Pen Society Decograph" fountain pen for 2019. According to the KK page for this pen, Paul Erano of the Black Pen Society collaborated with KK for this particular pen (not the Decograph style itself). The clip is a one-piece milled aluminum machined at a slight angle to help keep the pen securely in a shirt pocket. The finials on the cap and barrel are aluminum and are securely screwed in, according to the site. The body and barrel are machined from solid thermoplastic. The Decograph is said to be KK's lightest pen, weighing .72 ounces (20.4 grams). The pen's length is about 5.25 inches (about 13.5 mm).
The standard nib is a SS # 6 Bock with KK's own design on the nib face. For various premiums, one can order the Decograph (as well as all the KK FPs) with a titanium nib or a gold (14K or 18K) nib, and there are a decent variety of nib widths available. I chose the standard SS nib in a medium width, as right now KK is out-of-stock on some of the other widths (depending on nib material). If there were no stocking issues, I would have ordered a broad or stub.
The pen comes with a Schmidt K5 cartridge converter and two Monteverde ink cartridges.
For those who insist on posting their caps on barrels, one can post with the Decograph pens, but I wouldn't recommend pushing the cap on the barrel end too forcefully or too often. I don't think the designers intended for the cap to be posted. Posting would add weight that some pen uses desire, as this is a light-weight pen. I don't post my pens, unless they are very short without posting.
Whatever green you see in these photos of the BPS Decograph is only a reflection from a green object. This pen is all black.
Next are photos of the Deco Green FP. I've enhanced the coloration to compensate for my less than ideal photography conditions, so that what you see here color-wise is how the pen actually looks. This model has the same length and weight as the BPS Decograph above, so I need not repeat myself.
I filled my Deco Green through the converter with Krishna Elegent Teal ink. It wrote immediately with its medium SS nib without any issues. The nib has some springiness to it, and writing with a light touch is easy and very pleasant. The line it puts down is on the wet side, which I like.
Thus far, I am very pleased with this pen. The cost of each was $130 with just the standard nib.
