What is Kumiko?

Kumiko is a traditional Japanese woodworking technique that involves assembling intricate geometric patterns without nails or fasteners. Each piece is meticulously cut to fit together with precision, creating stunning designs used in screens, panels, and fine woodworking. The flat planing arm makes the CSMv1 an ideal tool for producing the thin, uniform blanks that Kumiko requires.

Tips & Notes

✓

The Chopstick Master Gen 1 (CSMv1) features a Japanese-style saw blade that is ideal for making the fine, accurate cuts required in Kumiko work.

Don't have the Gen 1 model?

No problem — you can achieve similar results by building a simple jig (such as a small miter box) to securely hold your blanks while cutting.

Whether you're exploring Kumiko, doing delicate inlay work, or just need precision thicknessing for small pieces, the flat arm adds an entirely new layer of versatility to your Chopstick Master setup.
