The Poseidon Knife Sharpening stone does require you to soak the stone before using to allow water permeate the stone. After soaking the stone, you are now ready to begin sharpening your dull knives. If you knives have a thick blade you can use the blade guide which comes with the kit. If not the guide will actually be in your way. If your knife has never been sharpened in the past you will start with the larger grit and work your way to the finer grit. Make sure to go in smooth motions when dragging the blade across the stone. Do one side then flip the blade and do the other side. Make sure to do the same number for runs on each side. Clean the blade with a clean towel and check for sharpness. Once you reached your desired sharpness you are done.
