{"type":"firestarter.listing","listing":{"id":"lst_-u8ZBI0Y","product_name":"Dao Vua V3 52100 Carbon Steel 240mm Gyuto","category":"Gyuto Knife","description":"Dao Vua V3 52100 Carbon Steel 240mm Gyuto\n\nDao Vua is a Vietnamese blacksmith cooperative born in 2016. When they first began, barefooted blacksmiths were using handheld angle grinders, buffers, and recycled leaf springs to make knives. Seven years later, Dao Vua has improved significantly from those days in every way. They now employ a proper workshop setup while continuing to adhere to traditional Vietnamese practices in blacksmithing and make use of higher quality materials such as imported 52100. Today, Dao Vua offers some of the best bang for your buck on the market.\n\n52100 steel is a high carbon steel originally developed for bearings over 100 years ago, but is also great for knives. Boasting good edge retention and great sharpenability alongside ease of workability, it is no wonder it has been a popular steel among knifemakers for decades - there is even evidence of recycled 52100 steel being used in cutlery as far back as the 1940s!\n\nProduct Specifications:\n\n    \nMaker: Dao Vua\n    \nSteel: 52100 Bearing Steel\n    \nHRC: 61\n    \nFinish: Kurouchi\n    \nEdge Length: 240mm\n    \nOverall Length: 393mm\n    \nHeel Height: 49mm\n    \nSpine Above Heel: 2.35mm\n    \nBevel: 50/50\n    \nHandle: Wa Shape Handle\n    \nWeight: 182 grams\n\n\nDao Vua Sharpening Service\nTo complement your purchase, we highly recommend our professional Dao Vua Sharpening Service.
