The finished brush head is fixed onto the handle. In the case of bamboo, it is warmed to straighten any distortion and curve, while the inside is hollowed to allow the bottom of the brush head to fit in and be glued. After the brush head is fixed to the handle, funori is abundantly applied to the brush head to ensure the brush head is maintained in good condition. Excess glue is scraped off using a string and then the brush is left to dry. The signature or brand is engraved into the handle using a special knife and a kamifuda (a small piece of paper) is adhered onto the handle.
