The quick sharpener completely changes the traditional sharpening method, changing the single-sided sharpening to double-sided simultaneous sharpening, which greatly improves the sharpening speed, and its unique sharpening angle makes the knife extremely sharp.
origin
1. The sharpening angle is fixed, generally about 30 degrees. The rough grinding angle of the sharpener is: 30 degrees, and the fine grinding angle is 30 degrees.
2. The sharpening speed is fast. Generally, an ordinary household kitchen knife can be sharpened in a few seconds.
3. Knife sharpening does not require any technology, and can generally be completed according to the manufacturer's instructions.
4. The shape of the sharpener is diversified. There are dozens of them on the domestic market.
Features
Sharpening material
Mainly divided into the following categories:
1. Cemented carbide (commonly known as tungsten steel)
2. Diamond (diamond)
3. 95# alumina ceramics
4. High-speed steel (the speed and effect of sharpeners of this kind of material are much worse than those of others)
5. Whetstone wheel (mostly brown corundum, which is used for rolling sharpeners currently on the market)
Selection essentials
1. Choose brand-name products produced by regular manufacturers as the main products.
2. For tools with high hardness (above RHA55), tungsten steel or diamond and ceramic sharpeners should be selected.
3. For high-end knives, tungsten steel or diamond and ceramic sharpeners should be selected.
4. Choose a sharpener that suits you. Don't believe that one sharpener can sharpen all knives.
