DFII. Dorsal Fin II Toki-Tamenuri * Nakaya

The Dorsal Fin II in toki-tamenuri has a special shape. By building up urushi lacquer on both sides of the pen, Nakaya created a kind of small sword. For Dorsal Fin II pens the waiting time is over 12 month's. So it is always special when they arrive. 

Tame-Nuri : "Tame" means "pool", and "nuri" refers to the lacquer coating process. You can actually see through the layers of clear Urushi lacquer to the underlying red Urushi base as if you were looking into a pool. Once the coating process is completed, the surface is polished over and over by hand to obtain greater transparency. The entire process can take several months. When the polishing process is complete, you see the coloured Urushi background even more clearly. The result is quite amazing. Over time, the lacquer layers will lighten due to exposure to daylight and become even more pronounced. The layers of varnish and the colour will then stabilise.
Important note: Urushi doesn't like direct sunlight, so keep your pens with their precious Urushi lacquer in a protected environment. A pen pouch, pen case or closed drawer is sufficient.
