Use the unglazed edge on the bottom of a pottery plate.

ANS2:Well, that would be like trying to drink water without water. Any thing or technique to sharpen a knife would be a sharpener.

If you are asking for a substitute for a whet stone, and you don't have a lot of respect for the knife, you could try a grinder or a file. Placing the blade in nitric acid will leave the edge sharp and jagged. If you have a lot of time, you could get some jeweler's rouge and polish the blade to a fine edge.
