“I splashed out on this nib (and it was an indulgence) mainly for art-making. While it's a decent nib for writing, because it lasts a long time between dips, its real strength is in the amazing variation of line thickness that can be achieved. In that respect it's quite similar to fude fountain pens and even the Pilot Parallel pens, but it's easier to manage than a fude and more fluid than a parallel pen.
I opted for the stainless steel version and, as others have noted, it has a pencil-like "resistance" to it, which I quite like. I don't feel like the nib is skating over the page and there's that little bit of control. Given the cost and relative fragility of the nib, I recommend pairing it with a Tachikawa model 40 pen holder, which comes with a cap, especially if you're planning to use it for sketching away from your desk.”
“The Kakimori SS bullet-style nib is excellent; however, limited in its application and more suited to testing inks, colour swatches and non-detailed sketching or text. The nib is flawless in its execution, and the quality, craftsmanship and use deliver on the hype. With one caveat, the reader needs to be into diarising and drawing to justify the expense. I got caught in the hype, purchasing the nib on an impulse rather than use case--you are warned, it's not a general daily writer.”
“Bought the brass one first but this steel nib doesn't disappoint! There is some feedback though, like writing with a rough pencil. The line variation is also not as prominent as with the brass.”
