In our daily lives, double-edged blades are often used for a variety of fine work, such as shaving, eyebrow threading, handmade and so on. Having a sharp double-edged blade can make our work more efficient and precise, and also improve the experience of using it. So how do you sharpen your double-edged blades?
First, understand the structure and material of double-edged blades
In order to keep a double-edged blade sharp, you first need to understand its structure and material. Double-edged blades are usually made of stainless steel, high-carbon steel and other materials, which have high hardness and wear resistance, and can maintain a sharp edge during use.
The structure of a double-edged blade generally includes a blade, a back and a handle. The blade is the key part of the blade, and its sharpness directly determines the use effect of the blade. The back protects the blade and increases its strength. The design of the handle affects the comfort of the blade and the stability of the use.
Second, the correct way to use
1. Avoid improper use
Improper use is one of the main reasons that lead to dull double-edged blades. When using double-edged blades, avoid excessive force, cutting hard objects or improper operations. For example, do not use a double-edged blade to cut metal, glass and other hard materials, so as not to damage the blade. At the same time, it is also necessary to avoid discarding or colliding the blade at will, so as not to cause damage to the blade.
2. Maintain the correct cutting Angle
When cutting with a double-edged blade, maintaining the correct cutting Angle can effectively extend the sharpness of the blade. In general, the cutting Angle should be between 15° and 30°, which can minimize the contact area between the blade and the object to be cut, thereby reducing the wear of the blade. At the same time, it is also necessary to pay attention to keep the direction of cutting consistent, avoid cutting back and forth, so as not to cause irregular wear of the blade.
3. Replace the blade periodically
Even if we take the right use method, the double-edged blade will gradually become dull after a period of use. Therefore, regular blade replacement is one of the important measures to keep the blade sharp. Generally speaking, the replacement cycle of the razor blade is 1 to 2 weeks, and the replacement cycle of the eyebrow blade is 2 to 3 weeks, and the specific replacement cycle can be determined according to the use of the individual and the wear degree of the blade.
Third, daily maintenance methods
1. Clean the blade
After using a double-edged blade, the dirt and residue on the blade should be cleaned in time. You can gently wipe the blade with a clean, damp cloth, and then dry it with a dry cloth. If there are stubborn stains on the blade, you can use a small amount of cleaning agent to clean it, but be careful to avoid contact with the cleaner to avoid damaging the sharpness of the blade.
2. Apply anti-rust oil
In order to prevent the double-edged blade from rusting, you can apply a layer of anti-rust oil after cleaning. Anti-rust oil can form a protective film on the surface of the blade to prevent moisture and oxygen in the air from coming into contact with the blade, thereby extending the service life of the blade. When applying anti-rust oil, pay attention to evenly apply to avoid too much anti-rust oil remaining on the blade.
3. Store it properly
The correct storage method can effectively protect the double-edged blade and extend its sharpness. When storing the blade, keep it in a dry and ventilated place, away from direct sunlight and damp environment. The blade can be placed in a special blade box or wrapped in a soft cloth to protect the blade from collision and damage.
Fourth, professional sharpening methods
1. Use a whetstone
A whetstone is a common tool for sharpening knives, which can effectively restore the sharpness of double-edged blades. When using the whetstone to sharpen the knife, the whetstone should first be soaked in water for a period of time to fully absorb water. Then, place the blade on the whetstone at an Angle of 15° to 20° and gently push the blade back and forth, taking care to keep the Angle consistent. In the process of sharpening the knife, water can be added to the whetstone in a timely manner to keep the whetstone moist. The number and intensity of sharpening should be determined according to the wear degree of the blade, in general, each side of the blade grinding 10 to 20 times.
2. Use a knife sharpener
The knife sharpener is a more convenient and quicker knife sharpening tool, which is usually composed of multiple knife grooves and can adapt to double-edged blades of different sizes and shapes. When sharpening the knife with the sharpener, just insert the blade into the sharpening slot and follow the instructions on the manual. The sharpening effect of the knife sharpener is usually not as good as the whetstone, but for some slightly worn blades, it can still play a certain repair role.
3. Have your knife professionally sharpened
If your double-edged blade is more worn, or you are not confident in your sharpening skills, you can consider having your knife sharpened by a professional. Professional knife sharpener usually has rich experience and professional technology, according to the material and wear degree of the blade, using the appropriate sharpening method, the blade will be sharpened more.
Fifth, Pay attention to safety
In the process of sharpening and maintenance of double-edged blades, we must pay attention to safety. Avoid cutting your fingers with the blade, and you can wear gloves or use tools to operate. At the same time, it is also necessary to place the blade out of reach of children to avoid accidents.
Conclusion
In short, if you want to make your double-edged blade sharper, you need to start with the correct use method, daily maintenance and professional sharpening methods. Only in this way can we ensure that the double-edged blade always maintains a good sharpness and brings more convenience to our life and work.
