Take your blade and look at the bevel; it's probably around 15°. Then take a fine carborundum, Arkansas, diamond, or other sharpening stone and, holding the knife at this bevel, push it firmly across the sharpening surface as if you were trying to peel its "skin" off. A few swipes should do it. Lastly, lay the flat side right on the stone and draw it back lightly to get rid of any "burr" or "wire edge". If you look at the blade with a magnifier you should see one flat cutting edge, lightly abraded. Any "polished" area at the tip indicates rounding which needs to be removed. Hope this helps.
