Ⅰ. The magnetic aluminum holder included in the set ensures stability and allows you to easily fix the sharpening stones. Its strength guarantee that using the sharpener will be comfortable and safe, as the knife blade will remain in the correct position throughout the sharpening process. This reduces the likelihood of errors and allows you to achieve professional results without additional effort. Ⅱ. Medium-grit diamond sharpening stones are extremely durable and effective. They quickly and accurately remove irregularities, restore the shape of the blade and give the knives cutting properties. Diamond surfaces are resistant to wear, therefore ensuring long-term use without the need to change sharpening stones frequently. Ⅲ. This sharpening set allows you to choose between 15 and 20 degree sharpening angles, which are suitable for different types of knives. The 15 degree angle is ideal for precision cutting knives, such as Japanese-style kitchen knives, ensuring a sharp and thin blade. The 20-degree angle is a choice for everyday kitchen knives that require durability and resistance to strong cuts. Ⅳ. Manual sharpening provides complete control and allows you to achieve a precise blade angle, which is often not possible with automatic sharpeners. This method allows the knives to maintain their optimal shape and prevents excessive material wear. This is especially useful for those who want professional-quality sharpening at home. Ⅴ. Ease of use and simple maintenance make this sharpener a practical tool in every kitchen. After use, it can be easily cleaned and stored compactly, so it does not take up much space. Durable materials ensure long service life, and the magnetic holder makes maintenance and organization easy.
