<human>:  What's the best way to sharpen a kitchen knife?
<bot>: The best way to sharpen a kitchen knife is to use a sharpening stone or sharpening steel. Make sure you use a light touch and apply even, consistent pressure as you sharpen the blade. Move the knife against the stone at a 15-20 degree angle. Start at the tip and work your way up the blade, applying the same amount of pressure and even strokes, until the knife is sharp.
