Keep edges separate.
Choose storage that protects the edge and makes sharp tools easy to identify. Check the blade dimensions against the holder or sheath. Avoid loose knives in a crowded drawer. Put products away clean and dry.
Consider the surface beneath.
Use a stable board suited to the cutting task. Glass, stone and metal can be hard on a knife edge. Use a scraper to move chopped ingredients instead of dragging the cutting edge sideways across the board.
