The black wax is called Matsuyani and is the sap of a type of pine tree, they don't say the name of the hand drill, the grain used to get the glazed finish called arashi is either some hard metal for the two on the left and hard sand called kongosha on the right. If you have any question feel free to ask.

Thanks for your reply. This was five years ago, I forgot that video, still interesting to see again. Can you also tell be about the process at 25:00, to darken the silver, it seems to be "gin furubi" or something like that, it's also funny after some years I understand a very bit better, for example, I heard "rokusho" process, easier to understand the word, when you know what the process is!

@@parfaitelumiere I wasn't sure you would still read your comments but i am glad you did. As you wrote it the process of oxidizing the silver is called Gin Furubi (literally, Beautiful old silver) or Tanpan Furubi and it is done by dipping the pot in a solution of copper sulfate (硫酸銅　ryuusando) then rinse it in water (actually rinsing it in smoked green tea is better), dry it to create a more aged surface. You repeat the process as many times as you wish to intensify the aged colour. It must be rinsed very thoroughly then dried than rinsed again. I guess you study Japanese because not many people would understand that video. I lived in Japan nearly 30 years so this is kind of a second language. But i still need to look up many words when i write. Learning Japanese is a never ending process. Ganbatte !
