The handle is crafted from premium ebony. It was acquired from a retired miyadaiku (temple and shrine carpenter) in the Chiba area, who originally purchased it 50 years ago and used it as his primary daily workhorse. Based on the proportions and geometry of the eye, it is unmistakably an early work by Kouzaburo.\u003c\/em\u003e\u003c\/strong\u003e\u003c!----\u003e\u003c!----\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-info__block-item\" data-block-type=\"quantity-selector\"\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eAccording to information provided by Tsuchida-san, Japanese genno (hammers) are traditionally classified into four size categories:\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eMame-genno (豆玄翁): Refers to 20 to 30 monme (approx. 75–112.5 g).
