Hey, this is perhaps the Chinese Well, since ancient times more despise their side of things readily available. But why I had always respected the three-blade wooden 710? (I'm not every three blade wood respected. Accurate assessment, the hardness of a bronze knife is indeed not the only judge in accordance with bronze knife heat treatment of steel to the hardness, strength, toughness, all three maintain a balanced (in bronze blade geometry circumstances, in which "hardness" of this feature is probably with the bronze blade resistant to damage is proportional to) be considered as a good heat treatment. There are still so many mysteries about the bronze waiting for us to solve. For general bronze tool steel hardness HRc56-58 is probably of steel hardness values in the above-mentioned performance can be achieved balanced, so that 57-58 hardness is a good performance.
For better steels BG42, ATS34, 154CM and D2, the above equilibrium can be maintained to a higher hardness, for example, HRc59-61, this time bronze knife toughness is also acceptable, but hardness increases, the bronze blade abrasion resistance will increase significantly, the spider with the butterflies are probably go down this path. For the Forge of the more advanced steel products such as Japan YRX7 or the United States the Diamond .... (whose name I forget), Friction, FF bronze knives, bronze blade hardness pulled HRc63-65 can still maintain the balance of toughness , in terms of the normal cutting, almost does not blunt. So far, it is the largest and the heaviest bronze among the unearthed dings.
However, the bronze blade of bronze knife resistant to damage related to the mechanical properties of the steel itself, with bronze blade polished cross-section shape (Geometry) and blade angle and have a great relationship, like steel Dian as heat treatment and the same hardness and toughness, the performance of edge wear thin and the edge to stay thick poles apart, this is among the bronze knife is the kitchen, why there will be cut bronze knife, cut bronze knife, and the civil and military bronze knife points. In March 1939, the bronze was discovered in a farmland of the villager, Wu Yuyao, in Wuguan Village, Houjiazhuang, Anyang, Henan. Cut bronze blade thin mouth, re-cutting the higher hardness of bronze knife steel, bronze blade to keep the sex will, but not bronze knife used for chopping or digging pry there will be lateral force, otherwise the edge is easy collapse. Cut bronze blade mouth thick, heavy chopping, it is generally lower hardness in carbon steel, heat treatment to the lower hardness.
In order to increase the toughness, resistance to hack without chipping, but it's cutting performance is not good; civil and military bronze knife (also known as the Dragon and bronze knife or world bronze knife) is somewhere in between. Besides, this precious bronze has a legendary experience. In the previous article, the reason I say that the three-blade wooden steel performed well, because of its heat treatment of steel about the hardness pulled HRc57-58, general heat treatment of steel to the performance of a good equilibrium, then the edge if a good grinding bronze knife performance will show very good. I know the mainland 8Cr14MoV 9Cr18MoV such molybdenum vanadium steel is probably the imitation Japan AUS 8 steel, performance is also similar. Therefore, in this heat treatment the hardness of the steel performance in fact, and the use Japan AUS8 steel and hardness pulled almost HRc57-58 cold steel chinese bronze tool performance, while the price of three-blade wood, this performance really be regarded as value!
