Why do some sharpening stones crack, use quickly, or have poor sharpening power?

Dear, do you have this puzzle when choosing the sharpening stone?

First, the product formula and production process will lead to different quality. White corundum whetstone is mainly made of white corundum, kaolin and feldspar in the corresponding proportions. The proportions of these three materials are different from different manufacturers. The research and development of GENFFY whetstone has gone through hundreds of experiments before getting a suitable ratio, taking into account the sharpening force and durability. There are many factor that affect product quality.
Here are some examples: ①If the proportion of white corundum is insufficient, it will lead to poor sharpening force; ②If the proportion of kaolin is insufficient, it will cause insufficient hardness after the whetstone is made, and use faster;③The white corundum whetstone needs to be fired at a high temperature of 2000 degrees for sufficient time. If the temperature is not enough or the firing time is not enough, it will also affect the quality of the product.

Second, the grade of white corundum is divided into superior, first grade, qualified and unqualified. The quality of superior products is better than that of first grade products.
GENFFY sharpening stone is superior grade.

GENFFY whetstone is superior grade, It adopts a high-quality formula obtained after hundreds of experiments. It does not cut corners in production, takes into account grinding power and durability. I believe you will not regret choosing us.
