How can I safely sharpen a kitchen knife?
assistant
To safely sharpen a kitchen knife, you will need a sharpening stone or a honing rod. Start by wetting the stone or rod with some water or mineral oil. Then, hold the knife with the cutting edge against the stone and pull it along the stone in a back-and-forth motion. Apply light pressure, and use a few light passes on each side of the blade. Repeat until the blade is sharp, and then wipe the knife clean.
