The Nakaya Dorsal Fin 2 Heki-tame is one of Nakaya’s most distinctive signature designs, combining sculptural form with traditional Japanese urushi craftsmanship. Inspired by the silhouette of a Japanese katana, its raised fins on both cap and barrel create an unmistakable profile while serving as practical roll-stoppers. These intricate contours are painstakingly built up and shaped by hand, reflecting the exceptional skill behind Nakaya’s unconventional design.
 
The Heki-tame finish brings further depth through its blue-green Heki-iro base and translucent tamenuri lacquer, creating subtle tonal variations that shift with the light. For collectors, the Dorsal Fin 2 represents Nakaya’s distinctive design philosophy at its most expressive—a remarkable union of Japanese lacquer artistry, thoughtful functionality and sculptural individuality. Its recognizable form makes it a particularly compelling addition to a collection of fine Japanese fountain pens.
