1.  Diamond V-grooves (600 grit): 17º, 20º, 25º and 30º

Holding the knife with your dominant hand, and using the other hand to hold the sharpener: pull the knife through the desired angle slot. Rinse blade after sharpening.


2.  Ceramic Benchstone

The medium (800) grit ceramic element should be used in a benchstone type fashion, or like a butcher steel. The ceramic benchstone is harder than steel, will never wear out, and can be used often as the primary sharpening element of your D-Sharp. The Ceramic Benchstone is also tapered for sharpening serrated knives.

Eventually metal shavings will accumulate as dark streaks on the ceramic and will slow effectiveness. Clean with a Lansky EraserBlock.


3. Sharpening Serrations 

Sharpen one serration at a time by pulling the ceramic element against the grooved side of the serration. For larger serrations: use a rolling motion to sweep the corner of the sharpener from one side of the serration to the other. Repeat until serration is sharp then move to the next serration.
