THE NATURAL SHARPEN STONE:
Nowadays, the tool that is used with this aim, is the metallic whetstone, which to sorrow fulfills it, because it has the power of sharpened very limited (if for sharpened we understand to eat up the quantity of remaining steel in the edge of the tool, so that the wedge that forms is the most perfect and thin as possible).
The metallic whetstone, it is practically made of the same material as the tool that is trying to sharpen, steel. The best whetstones that nowadays we can find in markets, when they eliminate the thin stretch marks that it has in his surface, lime effect, they become smooth and they can only manage to brush the dust that remains in the edge of a knife. It remains blunt withoand the whetstone can’t sharp properly.
When this happens, they normally use electric tool with emery stones of different grains, which they are capable of eating up the steel, but at the high price of disturbing the thin knife-edge of these. Using this process, it becomes necessary to repeat it every time with more frequency, with the result of battered tool and the professional with a problem who solves it buying another tool.
The natural sharpen stone, has many advantages, which do that his results are surprising. Remember the famous Sevillian razors that were sharpening with a piece of these stones and water. Then I will explain the problem they had.
Also they have a few disadvantages, they are used as a manual sharpen tools, so most of the people we have heard to talk about them but very few know them, and the ones that make them, they only know the use of these in pieces, not in a complete tool.
The disadvantages of the natural sharpen stones, are the derivatives of his natural origin, like “The fragility”, “The natural fissures” and especially “The weight”.
The advantages of the natural sharpen stones are:
In nature does exist an extensive variety of them, with different components, like the silica, the quartz and many hard minerals that also are not normally pure, what they are awarded by one of their suitable characteristics for their use in the sharpen, “The porosity“.
The natural components are in them, also in different particles sizes. So two stones with the same components but different particle size, do some of them suitable to empty the knife-edge and others to maintain it.
These components also have different thickness in the different stones,so the effects on the courting tools can be as different as the variety of the existing stones and the use we are going to give them.
The water absorption capacity awards to them the virtue of getting soaked in it and on having used it for sharpen, done it in humid and therefore in cold, and so maintain the tempering of the steel
Therefore, existing a natural product with so big advantages for sharpened of courting tools as it is “A PEDRA DAS MEIGAS”, due to the intrinsic disadvantages in his origin, it cannot be used like a common use tool, that is to say, as the whetstone is used by professionals.
HOW TO SOLVE THE PROBLEM?
To solve the problem of the fragility, and the natural fissures, we provide to the stone a rigid and inflexible soul (like for example a rod of 8 mm) made of stainless steel introduced and stuck down in the interior.
This allows us, at the same time, to make long and thin formats so we solve another problem “The weight”.
If we use one of the ends of the rod that we have left as a handle to grasp the stone so we already have a tool, “Save, Trustworthy, Resistant Lasting and Effective“.
The court process with professional silverware needs for several motives a useful one of manual sharpened. The motives are: the safety of the user, the quality of the product court and the maintenance of the tool in perfect state, sharpened and knife tempering.
