Nakaya Dorsal Fin Version 1 Ishime-Kanshitsu Suzu
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 either smooth urushi or stone texture Ishime-Kanshitsu finish. With either finish, this is one of the most memorable writing instruments Nakaya has produced.
In Suzu-ishime technique, tin flakes are mixed with dried urushi powder to create a textured stone-like finish with a unique silvery hue. The Dorsal Fin Version 1 showcases this unique finish as perhaps no other pen model can - except perhaps for the Dorsal Fin Suzu-ishime Version 2.
Each Nakaya pen is hand-turned from natural ebonite harvested from the rubber gum tree. Layers of natural urushi lacquer are then applied over a period of months to create the distinctive cap fin, which also serves as a built-in roll stopper.
Nakaya pens can be filled with bottled fountain pen ink using the provided converter. They can also use Platinum brand ink cartridges. Hand-painted Maki-e converters are also available, as are a wide range of other options and accessories.
