It was meticulously handcrafted about 5 years ago by the master blacksmith Hiroki Aida, showcasing exceptional craftsmanship. The length-to-width ratio of the hole in Yamakichi-style hammers is different from other high-profile hammers, usually falling just short of the ideal 3:1 ratio.\u003c\/strong\u003e\u003c\/em\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eThe reason I included the data on the eye's Vertical-to-horizontal ratio is as follows (particularly for large slender hammers):\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eIn the article 「\u003cspan\u003e「Shape of Carpentry Tools - About the Genno，[Part 3] Holes and Handle」, p38, Knife Magazine No. 10, 2010.\u003c\/span\u003e」 by Mr. Tsuchida Noboru, it is mentioned:\u003c\/em\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003e“To the extent that the strength of the handle tip can be maintained, it is best to make the eye as small as possible. An eye with a vertical-to-horizontal ratio of about 3:1 is, based on experience, considered an effective design. However, the more elongated, narrower, and smaller the eye is, the more advanced manufacturing techniques will be required. This is only natural, as a larger eye allows for a greater margin of error during the forging process.”\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!----\u003e","brand":"TENMOKU","offers":[{"title":"Default Title","offer_id":47854693286126,"sku":null,"price":18800.0,"currency_code":"JPY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/0162\/5326\/files\/DSF6151.jpg?v=1775351368","url":"https:\/\/tenmoku0701.myshopify.com\/ja\/products\/yamakichi-genno-japanese-hand-made-hammer-by-hiroki-80-monme-1","provider":"TENMOKU","version":"1.0","type":"link"}
