Suzuki Ittetsu Silk 015 May 2026

While primarily a calligraphy brush, the Suzuki Ittetsu Silk 015 is excellent for painting bamboo and orchid leaves in the literati style. The split tip capability (allowing Kasumi or misty strokes) is phenomenal.

You can’t talk about Japanese shears without talking about steel. The Silk 015 is forged from Hitachi ATS-314, a high-carbon, cobalt-enhanced stainless steel.

The Suzuki Ittetsu brand is a venerable name in Japanese stationery. They are historically known for their handmade Sumi sticks and traditional manufacturing processes. By bridging the gap between the ancient discipline of solid ink sticks and the modern convenience of liquid ink, they have created a product that satisfies purists and professionals alike. suzuki ittetsu silk 015

Ittetsu did not use traditional tipping materials (like Iridium). Instead, he ground the stainless steel or titanium directly into a long, tapered point. This creates a "naginate" (sword-like) geometry. The slit is often cut extremely deep into the nib to allow for a surprising amount of flex, despite the needlepoint tip.

For signing certificates or writing Nakagaki (medium-sized works), the Silk 015 is a reliable workhorse. It does not shed hair like cheaper brushes, and its silk fibers resist mold and breakage. While primarily a calligraphy brush, the Suzuki Ittetsu

If you are used to Western Medium nibs, the Suzuki Ittetsu Silk 015 will feel like writing with a lie.

Feedback: It is not smooth in the conventional sense. It produces a distinct, high-pitched "shrrrrrrrrp" as it moves across the page—a sound collectors call the "Ittetsu Whistle." This is feedback, not scratchiness. You feel the individual fibers of the paper as you write. The Silk 015 is forged from Hitachi ATS-314

Pressure: This pen is not for heavy-handed writers. Using 20g of pressure produces the 0.15mm line. Using 150g of pressure (dangerous) might produce a 0.6mm line. The pen encourages a meditative, floating touch.

Ink Economy: A single fill of the Silk 015 will last months, as the nib deposits microscopic amounts of ink. Dark, lubricated inks (like Pilot Iroshizuku or Sailor Jentle) work best; dry inks will cause immediate hard starts.

A common criticism of synthetic brushes is that they "drool" ink—releasing too much too fast. Suzuki Ittetsu solved this with the 015 by adding a 15% goat hair buffer in the belly of the brush. The result is a brush that holds a reservoir of ink for an entire 10-character poem, but releases it only under pressure.
