Nowadays, with the rapid development of science and technology, we no longer need knives to defend against the enemies in the war to protect our country. But the industrial civilization has been continuously developing by the means of a knife called cemented carbide knives. Why? Let’s see: if the blades with a more fast cutting speed could bring higher output, the higher output could increase the production volumes, and increased production capacity takes greater economic benefits to the manufacturers. Therefore, each country is scrambling to develop raw materials which can bring higher cutting efficiency to blades. Even if all we know is that carbide slitting knives is the top one at present.
Why would we say that the development of the knives has witnessed the development of industry, it is widely applied to various industries. From aerospace, oil drilling, and mining to toilet paper cutting, wrapping paper cutting, and so on.
