Behind Dogenzaka in Shibuya, Tokyo, there is a long-established store that has been selling carpentry tools since 1910 (1910). The owner, Kenzo Yoshizawa, is the second generation, who is small and looks good in Tsumugi kimono. Occasionally, his Edokko dialect pops out in a calm tone.
In the nearby Ebisu, there was a workplace for Mr. Ishido, a master craftsman of plane blacksmith, and he had a close relationship with the 9th and 10th generation Ishido, the first generation, and the third generation Chiyozuru, so he had good tools. I asked you to show it.

　"In the old days, when I saw work during my young age, my friends cut pillars and boards, showed each other's workmanship, boasted each other, and refined their skills. And as their arms gradually rise, they must ask for better tools, and they will come to us. If you can't beat him alone, your friends will come too hard. And then, it will be a whetstone. The last thing that determines the sharpness of the blade is the whetstone. The old man smiled, saying, "I'm going to be alone for the first time with my arms, knives, and whetstones."
