Steel hunting knife


Japanese Industrial Standard SKS-3/31 Steel material famous for being used by Randall steel. It is characterized by the goodness of the blade holder. The tool steel popular ultimately cutlery still struggle against this balance even today, [hardness] [tenacity] [wear resistance] [corrosion resistance].
Currently, it is likely to be a balanced blade steel with excellent corrosion resistance, so that American and Hitachi Metals are twinning. Although the steel material [D2] has had a wonderful balance, the resistance to corrosion is low and tends to rust.

ATS-34 the steel materials that Hitachi Metals has made world famous for the fame of YSS (Yasushigane) are proud of the world.
Special stainless steel with the best balance with resistance to oxidation.
Increasing the chromium to increase the resistance to corrosion, making carbon steel with high carbon content very sharp. It will be the best class in the world at this time. Loveless also uses this.
Carbon 0.97% · Chrome 14 ~ 14.5% · Molybdenum 4.0%
* According to the "Silver Paper" (Silver series) that should be mentioned as representative of Akagi Stainless Steel, molybdenum is added as filler, developed as a special steel for knives. The HRC hardness is 59 degrees or more, the retention of the blade is good and is very popular outdoors.
Representative knife steel material developed in the United States.
Especially strong against rust.
Carbon 1.0% · Chrome 17 ~ 18% · Molybdenum 0.45% Although
The SUS standard is the EE standard. UU. SUS [440-A] of Aichi Steel is also stainless steel 18 resistant to rust, also used for knives and other knives for diver.
the hardness is insufficient, so it will not be used for full-fledged cutlery. Steel with chrome of 11% or more is made of stainless steel, but SUS 304 and others are too soft for the same knife as 18 Krom, which is too soft. Only decoration knife and others because it is very resistant to rust, high quality material for kitchen equipment.

13 chromed stainless steel with 1.0% carbon and great sharpness is Takefu steel material [gold V gold]. But the cut is not an end. It can be difficult to make a blade because it is difficult. Well, it's better than [ceramic material] with abnormal hardness. I cannot do this. I do not know how to change in the future because I'm going in a certain way (hardness, etc.), but I still have a prototype perspective.
It seems that recently the evaluation of ZDP 189 is going up.
ZDP 189 steel alloy steel powder composed of extremely fine particles that has a high carbon content and can be stabilized at HRC-66 ~ 67 is also considered sharpness.
The cutting blade is sharp enough (thinner) the sharper it is. However, the thinner it is, the more fragile it will be. As a result, cutting steel with high wear resistance and high hardness (difficult to collapse) will be chosen. On the other hand, the hunting knives manufactured in Damascus also provide a high hardness, the contradiction arises that it is "difficult to lose weight". It can be said that the technicians constantly strive to "resolve the contradiction".
It would not be an exaggeration to say that "ATS - 34" was one of the objectives of that objective. That's why it was recognized by knife makers around the world. It is "ZDP - 189" that was developed with the objective of "more upwards" at the same time as this ATS - 34.
The finish that realizes the wear resistance of the hazard by the method whose manufacturing method is different from the root method (powder metallurgy), is strong and sharpens easily. It is stable with the HRC 65 hardness that far exceeds the overall carbon steel. For the moment, it can be said that it is the best class. However, this is not an "ordinary steel material", it is very expensive. In the case of a car, for example, it would be like "a super car."
ZDP 189, the Kauri X kitchen knife is manufactured by a famous door knocker shop around Sakai, but these things will be tailor made, so please consult with a reliable knife store. "Drunken Mr. San" or "Mr. Mr. Oshama" are ordering toys, but you can trust these two companies. Makes a solid ZDP 189 kitchen knife.
What is sharpness? It is the most important thing, but in fact there is no answer. There is a thing called "Honda-type sharpness test machine" that measures sharpness in a scientific way, and it is possible to quantify it with this. I think this is a very reliable figure. But, "It is human that cuts something" cannot solve this problem.
