<human>:  Can you tell me how to sharpen a knife without an electric sharpener?
<bot>: To sharpen a knife without an electric sharpener, you’ll need a sharpening stone or a honing steel. Start by laying the sharpening stone on a flat surface, and with the knife blade at an angle of about 20 degrees, use long, even strokes away from the edge of the blade. Move the blade from one side of the stone to the other. After a few strokes, check the sharpness of the blade. Repeat the process until the knife is sharp.
