How to Maintain the Sharpness of Your Knives
For a simple way to keep your knives sharp, store your knives in a self-sharpening knife block. This way, they will keep their level of sharpness with little to no effort.
For a more hands on approach, preventatively sharpen your knives before each use. This way, you'll never have to worry about cutting with a dull knife.
If your knife doesn't need to be sharpened, you're free to slice, chop, and mince as you wish, but if you notice the sharpness of an often used knife has faded, simply stop slicing and sharpen your knife right away. Now, you're free to slice whatever might hit your cutting board.
