In fact, in addition to the performance of bronze knife materials, bronze knife-shaped design has a great impact in terms of sharpness, the blade angle is smaller the more sharp, and the size of the blade angle also involves the main slant of the bronze knife the Primary Bevel way, if it is a very wide surface of the main incline Flat or the Hollow Glind way, that bronze knife itself is absolutely sharp and easy to use, CRK’s sebenza is the best example, but anti-break of the bronze blade may weak (but if not seen to have the heart to fold sebenza). This unique bronze was used to distinguish the high and low level and identity the rich and the poor.
Taiwan or mainland China to produce their own bronze knife, as if in order to save work and material, often the main bevel casually opened, causing the angle is too large, bronze knife is very difficult to sharpen, coupled with the blade angle of the Second Bevel open too much, that the original bronze knife with a blunt after discarding the average person is almost impossible then sharpened. Bronze knife bevel is very important, I found that even if the steel is not very good, but as long as the proper shape, the bronze knife can still be very easy to sharpen and maintain a very sharp, but his durability is not as heat treatment good steel material fills. Until now, people have realized why the bronze was so important to the ancients. But, so what? Just a minute or two can make him sharp as new, this is also something that is not another good program.
Finally, want to tell you that I personally feel good bronze knife material should have the condition, if memory serves me, Knife Talk, a book, the authors pointed out that the bronze blade should have the following four conditions, individuals also feel deeply Ran: With good strength, in order to maintain the bronze blade strength and bronze blades resistant to damage. Have a good hardness, in order to increase the wear resistance and bronze blade of bronze blade maintenance. With good toughness, bronze knife prone to breaking. The following brief introduction on the nature of the test method, first talked about the strength, the strength of the material (strength) in mechanical engineering or materials engineering field have a very strict definition. The time people were revering the value of ding, they were apt to forget the intended use of this bronze.
Usually based on the universal testing machine test rod or test film tension or compression experiments and obtained, and there are two different definition of the strength (yield strength and tensile strength), and take one of the application in accordance with the applicable areas. Tensile test, for example, ductile materials (such as steel, copper, aluminum and other metals) in the tensile elongation process, first of all will experience the process of elastic deformation, like a spring to stretch The strength of release, the test rod retracts to its original length. As a matter of fact, in the first place, this bronze was made as a cooking vessel to contain or cook food like pork. Tensile deformation over some key points, the material that will begin to permanent or plastic deformation, like the pull force of the spring force let go after there is no way to completely restore the original length.
The second bronze knife hardness – three blade wood 710. I did not expect an almost six years ago, the article stresses the bronze knife hardness caused by the response it did, being the case, apart from theory outside, to an actual example of good, like who? Three-blade wood 710. Bronze knife Friends of Q over why I think the three blade wood 710 the hardness HRc57-58 is a good bronze knife three blade wood 710 between the bronze knife Friends of the use of evaluation both good and bad, especially the mainland bronze knife Friends of, because The three-blade wooden, domestic, and their price is cheap, does not seem worthy of recognition like. It is a memorial chinese bronze of the Emperor of Shang to his mother (named Wu).
