<human>:  I'm looking for some tips on how to sharpen my knife.
<bot>: One tip for sharpening your knife is to use a sharpening stone. Start by wetting the stone with water or oil and then place the blade of the knife against the stone at a 20 to 25 degree angle. Using long strokes away from yourself, carefully slide the blade over the surface of the stone. Be sure to use both sides of the stone to sharpen the edges of the blade. After a few strokes, check the edge and repeat the process until the desired sharpness is achieved.
