That it is Chinese, was evident from the beginning (and in the pictures).
That it does not have instructions - it has Chinese markings on the product. We managed with the use of Google Translate.
It works very well. That's why I give it 5 stars.

Chinese like many other good already but this here does not have neither instructions nor any sign on the sharpening slots to understand what you will sharpen where... Money wasted even if it's a little...
