Frequently Asked Questions

What is the best type of knife sharpener?

For the sharpest edge and most control, a whetstone is best. For speed and ease, a quality electric or pull-through sharpener is more practical. The best choice depends on your knives and how much you enjoy the process.

Are electric knife sharpeners bad for knives?

Good electric sharpeners are fine for most kitchen knives, but cheap ones can remove too much metal. Avoid them for thin Japanese blades, and follow the angle the manufacturer specifies.

How often should I sharpen my knives?

Most home cooks sharpen every few months and hone in between. Frequency depends on how often and how hard you use the knife; our sharpening schedule tool gives a tailored interval.
