Edge Master 2 Stage Knife Sharpener features an ergonomic handle and nonslip rubber base for a safe and secure grip. If you find your knives are especially dull, use the coarse stage which features a diamond wheel, that will just remove that edge off. The fine stage features a ceramic wheel that will polish and hone the edge back to a razor-sharp finish. 

Highlights:

• 2 stage pull-through sharpener.
• Coarse diamond wheel.
• Finer ceramic wheel.
• Ergonomic handle.
• Nonslip rubber base.
• Ideal for recovering dull knives.
• Not suitable for serrated or scissors.
• Clean the sharpening rollers with a non-abrasive sponge or run a soft cloth through the rollers. 
• Do not rinse with water.
