Keep your Knives Clean

Warther kitchen knives are easy to clean - just rinse in warm soap water and/or wipe off with a damp cloth. Dishwashers are not recommended because the kitchen knives will become dull when the hand ground edge comes in contact with your silverware and in turn, the kitchen knives will scratch the silverware. The handles will lose their luster and become grey with exposure to the harsh detergents, heat, and water of the dishwasher.


Kitchen Knives are best stored in counter blocks, wall holders, magnetic bars, or in any other device that prevents the blades. edge from coming in contact with other utensils. Other utensils in a drawer will dull the fine cutting edge of your Warther kitchen knives.

Wood Cutting Boards are Best

What you cut on is almost as important as what you cut with. The cutting surface should not be so hard that it dulls the knife's edge. Corian, ceramic, and glass cutting boards are very hard and dull your kitchen knives. Some plastic cutting boards that are soft enough to see cut lines on are good, but a study at the University of Wisconsin-Madison indicates that plastic is more susceptible to bacteria growth than a wood cutting board. A good rule of thumb: If you cut on a wood cutting board, sharpen your kitchen knives once a year whether it needs it or not, if you cut on plastic, sharpen your kitchen knives once every two to four weeks and if you cut on ceramic or glass, sharpen your kitchen knives several times a week. Hardwood cutting boards are recommended to extend the life and sharpness of your kitchen knives.
