1.Grinding stone: The grinding stone generally chooses a long strip of flat fine stone with fine soft texture and moderate hardness.

2.Sharpening: Sharpening is a method that needs to be carefully experienced. First of all, it is necessary to understand the advantages and disadvantages of the steel clamping materials and quenching treatment of the tools used. For example, use the slurry stone on both sides to gently sharpen the knife.

It can easily break the steel filings, and when there are still small teeth with fine slurry stone grinding, it is mostly quenched too much, and it can be lightly annealed. The method is to heat the knife edge from white to yellow, that is, stop the fire, and the dry noodles cannot become blue, otherwise it will become too soft. If there are still small teeth, repeat it several times.

Some steels can't stand when the steel is too thin when the cutter is sharpened, and some steel is also thin when the cutter is sharpened. In this way, you can know the angle of the knife and the grinding surface in the sharpening.

The sharpening knife is generally made of fine slurry stone, not oil stone. When the new knife should be flat on the back of the knife edge, or when the knife edge is damaged and the amount of processing is large, you can first use 100 to 200 mesh crude oil stone and 200 to 300 mesh fine oil stone, and finally use the method of grinding the knife with fine slurry, the general traditional method is to pinch the knife body with the thumb and middle finger of the right hand, and the index finger presses the front end of the knife body, pushing and pulling. The wrist should be stable, and the angle between the knife and the grinding surface should be stuck and not changed.

Due to the clamping of steel, the number of times to be sharpened on both sides is equal, the grinding rhythm should be uniform, and the tension and relaxation should be combined. If the amount of processing is large, you can also hold the knife with the two fingers of the right thumb, and the remaining three fingers drag the knife body, and the index finger of the left hand helps the right hand to press the knife body, slowly push forward and press the heavy pressure, and quickly retreat backwards, and the knife is sharpened to a certain extent. Block a few times on the grinding stone to "fix the mouth", and then block the skin on the "mouth".

The angle of grinding knife is determined according to different knives, the back of the knife and the grinding surface are about 5, the angle of the adze knife is slightly larger, about 10 or so, the knife can be taken about 3 when lying flat on the grinding surface, the two corners of the knife edge should be sharpened to make it round, the drill needle is more difficult to grind, some masters used to make a groove on the grinding stone, now they do not use, the knife body and the grinding surface are 9 11, the right end of the blade is cocked into 2 3, the left end is grinding the surface, pushing and pulling and grinding, and then grinding the right end, the left end is warped, and finally the flat blade is kneaded and grinded, and then turned over and grinded the other side, The method is the same, the number of grinds on both sides is equal. You can also take a slender oil stone, hold the knife in your right hand, press the blade on the side of the case, the blade is cocked, and hold a small grinding stone in your left hand to sharpen the blade, and the angle is easy to grasp.

About the method of sharpening knives:

There are knife stones and oil stones, coarse stones and fine stones, depending on the different use of knives. In daily life, we find that many masters say that the knife is not sharpened quickly, and suspect that the knife itself has a quality problem, but in fact, it is not. Let's talk about the method of sharpening knives from personal experience:

1.Before grinding, the knife stone is soaked in water for 15 minutes, fully absorbing the water, and taken out when grinding, not dry grinding.

2.The knife stone is placed in a long direction, and the knife is at an angle of about 30 degrees.

3.Hand grip: Hold the upper middle of the knife with the index finger and fingerless fingers of the left hand, and hold the back of the handle with the right hand.

4.The knife is in a long direction on the knife stone, pushing and pulling back and forth, key attention: do not press hard when pushing forward, do not press hard, and press down hard when pulling back. If you push forward, the blade will be sharpened off, and the surface of the knife will be scooped up, damaging the knife stone.

5.The knife should be sharpened to the edge, in the process of grinding, the two sides are repeatedly grinding each other, while grinding while observing, there will be a layer of mangs on the knife edge, after the mangs are grinded out, there is a front. The edge will be revealed, that's the principle.

6. For some tools with extremely high hardness, such as blade hacksaw blade, tungsten steel, etc., the machine grinding wheel is sharpened, and after grinding the oil stone, it is necessary to use metallographic sandpaper for slight processing, and pull back a few times on the sandpaper, so that the tool will be extremely sharp.

15 degree angle, don't shake around, the number of times on both sides is the same, first take the coarse stone on the back of the fine stone, the knife will be fast.

The grinding angle of the blade in the opposite direction should not be too high.

The whetstone should be prepared on both sides, one for sharpening the knife and cutting the edge. After the knife edge is opened, change to another piece to close the edge. Only one piece of grinding is not closed, and the effect of sharpness cannot be achieved, and if you want to be sharp, you still have to grind back and forth with two pieces.

The material of the whetstone is made of oil stone, which should be smooth and delicate to the touch, and there is no pothole feel on the whetstone, and the size is appropriate, and the size of the knife should be able to be put down, and it does not show a crowded feeling. After the first whetstone is sharpened, remember the number of times you make a circle and then change to the second whetstone, in the same way as the first one.

There are two kinds of grinding stones to be used in combination, one is the grinding stone for the cutting edge, which is relatively rough and the oil stone for the closing is very fine.

If possible, it is best to grind some slurry in the block of slurry to help sharpen the speed and toughness of the knife.

Oil stone and natural whetstone are used together.
