<human>:  How do I properly sharpen a serrated knife blade?
<bot>: To sharpen a serrated knife blade, you should use a sharpening stone or a serrated knife sharpener. To begin, run the stone or sharpener along the inner part of the serrated edge of the blade, using small strokes. Start from the heel of the blade and work towards the tip, using the same number of strokes on each serration. Next, check the blade for any burrs or nicks, and repeat the strokes with the stone or sharpener if needed. Finally, use a leather strop or honing rod to polish the serrated edge and remove any minor imperfections.
