I consulted Mr. Tsuchida about this unique type. He explained that this is a more traditional design, which is heavier than modern versions. Notably, the blade's tip is positioned closer to—or exactly on—the center line of the handle eye. Compared to modern versions, this traditional chouna features a longer and heavier blade with a unique geometry. This design excels at removing larger volumes of wood, making it a highly efficient tool specialized for roughing work.\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eAdditionally, Mr. Tsuchida mentioned that this blade is exceptionally old and likely forged from Watetsu and Tamahagane. Just as he predicted, I was able to confirm this during the sharpening process a few days later.
