Furniture makers are known as sashimono-shi (指し物師), and interior finishing carpenters, who build shōji (障子) and ranma (欄間), are termed tateguya (建具屋).
[4] Though it is rare to find a sashimono-shi or tateguya practising outside of their field, it is not uncommon for a carpentry workshop to work simultaneously as both miyadaiku and sukiyadaiku.
When sharpening a blade, a Japanese carpenter will typically use three or more whetstones of varying coarseness, progressing from the roughest stone to the finest.
This then improves the precision with which cuts can be made by the chisel, and in the case of planes ensures smooth contact with the wedge and therefore even support across the full width of its blade.
The hollow also greatly reduces the amount of metal needed to be removed to achieve flatness on the back of the blade, which shortens initial set-up and subsequent re-sharpening considerably.
Woods used in Japanese carpentry and woodwork, as well as tool construction, include sugi (杉), akamatsu (赤松), hinoki (檜 or 桧), Camphor Laurel, Magnolia obovata, keyaki (欅) and kiri (桐).
