Attach the sandpaper to the piece of wood with the bull clips, and place on top of a wet kitchen towel so it doesn't move around.

Put some water on top of the sandpaper and you are ready to start.

Place your knife on a 10 to 15 degree angle in relation to the sandpapaer and move up and down to sharpen the knife, do the same thing to the other side of the blade.

And it's that easy, even Macgyver will be proud.
