- Does it work on serrated knives?
- No. The roller slot is meant for plain-edge knives. Serrated blades need a tapered rod or a serrated-specific sharpener.
- Is it better than a whetstone?
- It is easier and faster for a quick touch-up, but a whetstone gives a sharper, smoother edge with more control. Use this between proper sharpenings.
- Does it need water or oil?
- No. It is a dry sharpener; just draw the blade through the rollers and wipe the body clean.
- Will it damage my knives?
- It removes a small amount of metal with each use, like any sharpener. Use light pressure and few passes to limit wear.
- Can it sharpen ceramic knives?
- No. Ceramic blades are too hard for this sharpener and need a diamond abrasive.
- How do I know when to replace it?
- When the ceramic rollers feel smooth or stop restoring an edge after several passes, the abrasive is worn.
