SHUX bavarian knife sharpener Premium Sharpeners, Kitchen Knives, Outdoor Knives, Scissors, Damascus Knife and Ceramic Knives, Safe and Hygienic, Essential for Modern Household Kitchen Supplies(Black)

This device is hard to use. I bought it for the scissors sharpener and that only dulls scissors. Doesn't work at all for kitchen shears. The knife sharpener works OK, but not as well as one I already have.
