Tezumi Kusenaoshi Matcha Whisk Shaper

A kusenaoshi is designed to restore and maintain the shape of your bamboo matcha whisk (chasen). Over time, the delicate bamboo tines can warp or lose their curvature; this tool forces them back into their original, optimal alignment.

While ceramic holders are common, this wooden version is specifically engineered to correct both the outer and inner tines. The interior geometry is precise enough to guide the inner circle of tines back into place, which many standard ceramic holders fail to do.

We recommend using it primarily for reshaping rather than long-term storage. It is best to let your chasen dry standing up in the open air to ensure proper airflow and prevent mold growth on the bamboo.

After rinsing your whisk, gently press the wet chasen into the kusenaoshi. Leave it in place for a short period to allow the bamboo to set into the correct shape as it dries, then remove it to finish the drying process.

This shaper is designed to fit standard-sized bamboo chasen. If you have an unusually large or specialized whisk, the fit may be tight, but it is compatible with the vast majority of traditional Japanese whisks.
