Frequently Asked Questions

Q: What is the difference between the 15° and 20° sharpening angles on this knife sharpener?

A: The 15° angle is ideal for thin, precision blades such as Japanese-style knives and fruit knives that require an exceptionally fine, razor-sharp edge. The 20° angle is suited to most standard kitchen and chef's knives, providing a durable, versatile edge for everyday cooking tasks. Simply select the angle that matches your blade type for the best result.

Q: Do I need prior experience to use this diamond roller knife sharpener?

A: Not at all! The magnetic angle roller guide automatically holds your knife at the correct sharpening angle, making it straightforward for home cooks and beginners. Simply place the blade on the roller at your chosen angle (15° or 20°) and draw it gently across the diamond grindstone — the tool does the guiding for you.

Q: Can this sharpener be used on scissors and bread knives, not just standard kitchen knives?

A: Yes! This double-sided diamond sharpener is compatible with a wide variety of kitchen blades including bread knives, fruit knives, scissors, and general kitchen cutlery — not just standard chef's knives. The dual grindstone design (coarse + fine) makes it adaptable for both heavy-duty re-edging and fine finishing on multiple blade types.
