Sharpening a serrated knife is different than a sharpening a traditional straight blade because each serration needs to be sharpened separately.
To sharpen a serrated knife, use a ceramic hone and apply firm pressure, working the hone in a back-and-forth motion, perpendicular to the cutting edge. Feel for a raised burr on the backside of the blade every few passes to identify when you've reached the true edge. Once you raised the burr, continue on to the next serration until you have completed sharpening the ground side of the blade. Flip the knife over and use the hone to lightly remove the burr. Only the ground side of the serrations should be sharpened. After the burrs have been eliminated from the back side, what you have should be a revived serration pattern that is ready for more aggressive cutting action.
