That said, the heat treatment is excellent, with a uniform microstructure and good toughness. However, since the toughness is slightly lower than most Kiyotada chisels, you might need to increase the bevel angle when working with hardwoods.\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eI also verified with Mr. Tsuchida that Kiyotada chisels generally use White Steel No. 2 (Shirogami #2), while Ichihiro primarily uses White Steel No. 1 (Shirogami #1). Speaking strictly of the steel itself—excluding the influence of the blacksmith's technique—White Paper No. 1 is harder, while White Paper No. 2 possesses greater toughness.\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003c!----\u003e","brand":"TENMOKU","offers":[{"title":"Default Title","offer_id":47792279290094,"sku":null,"price":25000.0,"currency_code":"JPY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/0162\/5326\/files\/DSF4696_8d78027a-18a9-4c18-825f-23dfc9ae02cc.jpg?v=1773885101","url":"https:\/\/tenmoku0701.myshopify.com\/zh\/products\/oire-nomi-japanese-hand-made-bench-chisel-by-ichihiro-%e2%85%b1-30mm","provider":"TENMOKU","version":"1.0","type":"link"}
