"Shin" Purple Bamboo Chasen — Handcrafted Matcha Whisk

The Art of the Whisk

The Shin is not just a matcha whisk — it's a hand-forged instrument shaped by centuries of craftsmanship.

Carved from rare purple bamboo (zizhu), the Shin chasen develops a rich, dark patina that deepens with every use. Its 80 precision-split tines fan out to break up matcha powder with exceptional efficiency, producing a silky, lump-free bowl with a thick, even froth that flat whisks and machine frothers simply can't replicate.

What sets the Shin apart:

• Rare purple bamboo: denser and more durable than standard white bamboo, it holds its shape longer and resists splaying
• 80 tines: more contact points mean faster, more thorough whisking with less effort
• Black thread binding: hand-wound at the base for structural integrity and a refined, traditional finish
• Engraved squirrel handle: brut tea's signature mark, laser-engraved on the lacquered bamboo handle

Protective storage canister included — keeps the tines perfectly shaped between uses; doubles as a display piece

Whether you're preparing usucha (thin matcha) or koicha (thick matcha), the Shin performs with the precision and luxurious feel of a professional-grade chasen. It's equally at home as part of a full matcha whisk set or as a standalone upgrade to your morning ritual.

Whisk care instructions

Before your first use: 

Soak the tines in warm water for 10-20 minutes.

How to care for your chasen:

Soak the tines in warm water for 30 seconds before use to soften the bamboo. Rinse gently after each use — never submerge the handle. Store upright in the included canister to preserve the tine shape.
