The M390 by the Chinese good (send a good card) friendship to provide, residual samples are in, to ensure true.
Details:
This M390 with the "shrinkage process", slightly lower hardness 2HRC, mainly to verify the theoretical problem. So one to the province of labor, and second can look at the excellent powder steel (carbide), the third is to compare some of the "2 HRC" technical details and performance differences.

For the first time because the tip is too narrow, the results from the tip of the collapse of flying.
Can be seen in the middle of the remaining size, calculate the aspect ratio.
This aspect ratio, if the exchange, and then count the coefficient, such as the production process access, batch access, knife type, whether to open V and so on. Can be said to be straight (30cm), the thickness of about 5mm, you can limit to 90 degrees or so.
A blue line of one centimeter.
LS process experience:
The video has two D2s, which are the same as the reference effect, the routing principle is the same, but the LS process effect is not highlighted by the M390. In addition to the impact of thickness, it should be related to powder metallurgy, powder metallurgy process, really did not have to say, even if P, S accounted for high, still show better than ESR (P, S) better. In my chat with the engineers, as well as the information and my own tests, also confirmed that Mainly powder steel carbide shape is better, so even if P, S a little bit, you can win.
Subjective small test, heart to stay at the end, the results are expected within. And then looked at the carbide situation, also very good.
Although I can not afford powder steel, but really good, there are also powder steel, however. The The Take the volume is really moving.
LS process I began to think that in this line is not out, or that the effect is poor. The results of polarization, or very unexpected. M390 get, and expand some of the scope of application, such as you can do a long M390 sword, which in the past is not easy to achieve. Down the specific is the theoretical test after the optimization of the production process. Ah ~ ~ ~ suddenly remembered no one looking for the amount, it is not optimized, hee hee ~ ~ ~
PS: If you can not understand why you want to break the bend, you can read the old posts, or consult the elderly. A word explanation is: the use of deformation to absorb the impact of power!
PS: If the money is so good, I can use the powder steel to make a big knife.
