Japan Tool grinding technique, is a very complex manual skills, good research a good knife-edged research division, time can be as long as several months, because it is not just a simple knife sharpening.
Japan is a volcanic country, Japan grinding knife whetstone there are many lava, Japanese and even specially developed a lot summarized grinding stone veins, some of which mesh up to 6,000 head, is extremely delicate. Of course, these stones price is quite expensive, usually denominated in grams, ordinary people can not afford, which is why the ancient Japanese warriors and nobles will usually only one of the reasons samurai sword used. Because Katana routine maintenance costs are too high, even now, a Japanese sword most common grinding costs, they have to spend a month’s salary Japanese.
Here, we take a look at a good teacher is how to carry out this research work it.
Weight in grams of fixing prices within Tan whetstone. This is not aniseed before cutting, you must carefully choose when to use the stone ribs, cut into small pieces using a thin, otherwise it will scratch the polished good tool to rework lead to naught. Serious injury case, or even start from scratch.
Every knife made division has its own style, for example, where he used the ore, smelting what way, how reclaimer, forging, hardening, almost all of them different. These differences can also be expressed by the research division of the grinding ability.
After a good research division got a knife, he was not the first time have to move the hand, but the eyes and brain. He must first determine what time it is, who works at least what genre works, observe what defects and damage, and then decided what research method, in order to better demonstration of the knife on all content. Of course, it can not be determined, the next step may be performed, but this is not guaranteed outstanding work style to make it more distinctive characteristics of this point.
According to the present Ami family argument, research division got a knife, not to attack first, but should look at the ten days, or even twenty days until fathom this knife to do it. It has been almost a Zen.
Therefore, a good research division, first division must be a bit of art appreciation, to the history of the personal style of each genre and Cutler overripe in the chest.
The first stage of the grinding operation, is a modified plastic. The steps of this stage how much, because there is a certain difference between the different objects. For example, the new forging a good knife and knife regrinding finished, there is difference. New office knife, do not go in depth and possible surface rust blade of rust, but to correct some of the flaws forging, such as forging marks or pick lines are not straight, etc., which need to use a number of tools and processes. The antique knife there may be some other problems, such as scoliosis, can not be recycled nor cold forging, or will seriously damage the cutter body and even change the crystal structure, it is a very technical examination process. Specifically how to do, and that is the secret of their research division, in order to respect their efforts and crystallization, I keep a little mystery of it.
After the initial surgery, is the beginning of a real sense ground.
From this point onwards, the Japanese sword polishing usually divided into two phases and seven steps process to use a variety of whetstone and other materials. I am here to say, in fact, is a relatively simple process.
