There are many types of sharpeners, including fixed-angle, flat and rod-shaped, etc.; sharpeners are made of diamond, high-performance ceramics, cemented carbide, and whetstone, etc.; different products have large price differences. So how can I choose my own and satisfactory knife sharpener? We can discuss from several aspects for your reference when choosing:
First, the material and hardness of the knife or tool:
If your knives or tools use better steel, or have greater hardness, diamond sharpeners, high-performance ceramic sharpeners and whetstone are available; if your knives and tools are made of alloys that are harder than steel For materials, choose diamond sharpeners, high-performance ceramic sharpeners, and diamond sharpeners are especially recommended (for example, for grinding ceramic knives or cemented carbide cutting tools, diamond sharpeners are the best choice).
Second, single-edged tool or double-edged tool:
If you need a grinder that can be used with both double-edged and single-edged ones, they are generally regular flat and rod-shaped. Generally it is a diamond sharpener, a high-performance ceramic sharpener or a whetstone. But these all require certain sharpener skills. There are also tools that can be dedicated to single-edged or double-edged tools. These sharpeners generally do not require too much skill, but generally cannot be used in common between the two.
Third, the sharpness of the knife or tool:
If the sharpness of knives and tools is generally required, it is recommended to use cemented carbide sharpeners and diamond sharpeners for quick sharpening, especially fixed-angle sharpeners. If the sharpness of knives and tools is high, it is better to use high-performance ceramic sharpeners or whetstones.
Fourth, consider for each use occasion:
If you are an ordinary knife sharpener at home, it is recommended to use an ordinary cemented carbide fixed angle sharpener, which is fast, simple and hygienic. If you use high-end tools, it is recommended to use diamond wheels or "X"-shaped fixed-angle sharpeners. If you are an outdoor knife friend, the first recommendation is to use a universal fixed-angle sharpener or high-grade oilstone.
