Nakaya Dorsal Fin Version 1 Heki-tamenuri
The Nakaya Dorsal Fin Version 1 is one of the most innovative and distinctive designs created by Nakaya. Layers of Urushi lacquer are applied over a period of months to create the fin on the cap, and the surface is then completed with smooth Urushi finish. This is one of the most memorable writing instruments Nakaya has produced.
This finish highlights the sleek minimalism of this pen - form and function are united in an exemplary manner. The Heki-tamenuri color is a beautiful earthy brown with surprising bursts of green where the color shifts subtly, like welcome patches of grass peeking out from the soil after the rain.
Multiple layers of urushi lacquer are applied over a period of months to create the raised fin - this is one of the most time-intensive proceedures utilized by Nakaya.
Beyond its distinctive appearance, the Dorsal Fin is also a terrific everyday writer; the balance is superb. Nakaya pens can be filled with bottled ink using the provided converter, and can also use Platinum brand cartridges. Hand-painted Maki-e converters are also available.
Green highlights show through at the barrel and cap edges and along the top of the fin. These gradual color changes will become noticeable over time as the layers of urushi lacquer mature.
