Manufacturers would have you believe their hooks cannot possibly be any sharper than they are out of the package. While chemically sharpened hooks are a vast improvement over their mechanically sharpened predecessors, any hook can be made sharper.
1. Fold a piece of 1,000-grit wet/dry sandpaper into a small square and wet it.
2. Holding the hook in one hand, gently stroke the point of the hook with the sandpaper, going past the point and off. Never work back against the point.
3. Don't apply too much pressure, and never sand the point, as this will damage it. A gentle stroking action removes any imperfections and hones the point to perfection.
