Made from 3 mm thick stainless steel, the ruler is hand-forged and then hammered to create its distinctive textured surface. Its substantial weight and traditional metalworking finish give this everyday tool a distinctive character.\u003c\/p\u003e\n\u003cp\u003eThe measurement scale is laser-engraved, with major numbers represented by \u003cstrong\u003etraditional Japanese kanji numerals\u003c\/strong\u003e. Each size features its own set of markings: zero, five, ten, and fifteen on the 170 mm; and zero, five, and ten on the 140 mm. This distinctive detail gives the ruler a connection to Japanese craftsmanship while keeping it practical for everyday measuring.\u003c\/p\u003e\n\u003cp\u003eForging the stainless steel at high temperatures creates natural brown-to-black surface tones. With use, some areas may wear to reveal the silver steel beneath. Each ruler is handmade, so variations in colour and small processing marks are part of its individual character. Stainless steel forged at high heat is not completely rust-proof. If a powdery surface rust appears, simply wipe it off with a cloth.\u003c\/p\u003e\n\u003cp\u003eChoose between the \u003cstrong\u003e140 mm overall length\u003c\/strong\u003e, with a 130 mm scale, and the \u003cstrong\u003e170 mm overall length\u003c\/strong\u003e, with a 160 mm scale. Each ruler comes with a snug-fitting genuine leather case for protection and is presented in a paulownia wooden box, making it a thoughtful gift for stationery enthusiasts and admirers of Japanese metalwork.\u003c\/p\u003e\n\u003chr style=\"margin: 40px 0;\"\u003e\n\u003ch2 style=\"text-align: center;\"\u003eA Closer Look at the Texture\u003c\/h2\u003e\n\u003cp style=\"text-align: center; max-width: 700px; margin: 0 auto 24px;\"\u003eWatch this short clip to see the ruler's fire-forged texture and traditional kanji scale up close.\u003c\/p\u003e\n\u003cdiv style=\"max-width: 600px; margin: 0 auto;\"\u003e\n\u003cdiv style=\"position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; border-radius: 4px;\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/v6toTuCvARI?start=356\u0026amp;end=390\" style=\"position: absolute; top: 0; left: 0; width: 100%; height: 100%; border: 0;\" title=\"Kurogane Kazura Hand-Forged Steel Ruler\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003cp style=\"font-size: 0.9em; margin-top: 10px; text-align: center;\"\u003e\u003cem\u003eClose-up view of the hand-forged hammered finish and traditional kanji scale.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Inoue","offers":[{"title":"14 cm","offer_id":50758336250073,"sku":"KHC-140","price":189.0,"currency_code":"USD","in_stock":true},{"title":"17 cm","offer_id":50758336282841,"sku":"KHC-170","price":229.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/1173\/3209\/files\/Kurogane_Kazura_Hand-Forged_Steel_Ruler.png?v=1792397709","url":"https:\/\/penandtool.com\/products\/kurogane-kazura-hand-forged-steel-ruler","provider":"Pen \u0026 Tool","version":"1.0","type":"link"}
