You do this by not sharpening too much too quickly and by dipping the steel in water between sharpening rounds to cool it down. When steel gets hot it changes color, so you know when it has gotten too hot. At about 200 degrees the steel becomes golden yellow\/straw colored, then the effect of the hardening is reduced or destroyed, if the temperature gets higher the color becomes browner, then purple and if the temperature goes up further the steel turns blue.\u003c\/p\u003e\n\n\u003cp\u003e\u003c\/p\u003e\n\n\u003cp\u003e The steel piece is 3.25x50x280mm\u003c\/p\u003e","brand":"Laurin","offers":[{"title":"3,2x50x280mm","offer_id":45177601097981,"sku":"HERDET80CRV2-3.25x","price":322.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2148\/6651\/files\/IMG-1052.heic?v=1720646988","url":"https:\/\/storbua.se\/en\/products\/ferdig-hardat-knivstal-till-a-tillverka-kniv-80crv2","provider":"Storbua.no","version":"1.0","type":"link"}
