It is understood that in September 2017, the total output value of Japanese knives is about 34.143 billion yen, which is an increase of 8.4% from 315.04 billion yen in August, compared with 32.596 billion yen in the same period in 2016.

In addition, in the third quarter of 2017, the total number of Japanese carbide cutter output was about 99378 million yen, a 3.8% increase from the previous month, with the carbide cutting tool of 67.959 billion yen and 19.5%. High-speed steel tools were 218.88 billion yen and 28.2 percent less. Diamond cutter 28.8.3 billion yen and 12.2%; The cubic boron cutter was 6648 million yen,up 15%.

In September, the output value of Japan's carbide cutting tool was 23.271 billion yen, up 1.08% from the previous month and 20% year-on-year. The production value of high-speed steel tools was 75.79 billion yuan, up 9.1% from the previous year and 26.6% year on year. Diamond tool output is 10.07 billion yen, up 14% from the previous year and 10.3% year on year. Cubic boron cutter is worth 22.86 billion yen. Growth was 11.7 per cent quarter-on-quarter and 16.4 per cent year-on-year.

In the first nine months of 2017, the total number of Japanese bladeproduction was about 295.31 billion yen, up 0.2% year on year. Among them, the accumulative total of hard alloy knives is 14.5 billion yen and 14.5%. High-speed steel cutter 66.28 billion yen and 28.5%; Diamond cutter 8435 million yen and 6.7%; Cubic boron cutter was 19348 million yen and 5.3 %. It appears that the high speed steel cutter is a significant drag on the growth of the entire tool industry.

High speed steel cutter is a kind of toughness than ordinary knives, easier to carbide cutting tool, used to drill, tap, saw blade and hob, pinion cutter, broach and other precision cutting tools, especially suitable for manufacturing complex thin blade and impact resistance of metal cutting tools. In 1923, the emergence of the carbide makes the cutting speed increased to more than one hundred meters to hundreds of meters per minute, and its hardness is higher, which can be processed by high speed steel cutting materials, and with the constant improvement in recent years, the performance of cemented carbide, carbide cutting toolsgradually eroded the market share of high speed steel tools. Then there are more advanced cutting tools, such as ceramics, cubic boron and synthetic diamond, and they are more rigid and resistant than hard alloys.

High speed steel tools have excellent strength and toughness, while tungsten carbidecutting tools are superior in hardness and red hardness (the ability to maintain hardness under the cutting temperature). Generally, the cutting speed of the solid carbide tool can reach at least four times the cutting speed of the high speed steel cutter, and the tool life is longer. However, compared with high speed steel tools, the fracture toughness of hard alloy cutter is poor, which limits its application in certain machining areas, especially tapping.
