Marble stone high-hardness carving knife

The utility model discloses a marble stone high-hardness carving knife which structurally comprises a base, a material layer is arranged on the inner side of a knife head, a wear-resistant layer and a hard layer in the material layer are the same in thickness, and a powder layer is composed of diamond particles and tungsten carbide powder. Diamond is well known to be the hardest material in the prior art, and tungsten carbide powder has a very high melting point, so that the service life of the tool setting head is prolonged; the wear-resistant layer is made of a silicon carbide material and is formed by smelting quartz sand, petroleum coke, sawdust and other raw materials through a resistance furnace at a high temperature, and the manufacturing cost of the carving knife is reduced due to the addition of the material; the hard layer is made of a tungsten carbide material, tungsten carbide is a compound composed of tungsten and carbon, has metallic luster, is similar to diamond in hardness, is a good conductor
