How often should I sharpen my kitchen knives?

Most home cooks need to sharpen 2–4 times per year. Honing before each use extends the time between sharpenings significantly. If tomatoes squish instead of slice cleanly, it's time.

Will a pull-through sharpener ruin my knives?

It won't ruin them, but it removes more metal per pass than other methods. This shortens knife life over years of use. For expensive Japanese knives, use a whetstone instead.

Can you sharpen serrated knives?

Yes, but only with a sharpener designed for serrated blades (a tapered rod or the Work Sharp E5). Standard flat abrasives won't reach the serrations.

Best Knife Sharpeners in 2026: Every Blade Razor-Sharp

A dull knife is more dangerous than a sharp one — it requires more force and slips more easily. Most home cooks sharpen their knives once a year at best, which means they're using 50% of the knife's potential and fighting their cutting board the whole time.

Here are the best knife sharpeners of 2026 across every method: pull-through for speed, electric for effortless consistency, and whetstones for the best possible edge.

What to Look For

Electric vs. pull-through vs. whetstone: Pull-through is fastest and easiest but removes the most metal. Electric gives consistent results. Whetstones take practice but deliver the sharpest edge and remove the least material.
Grit stages: Coarse (100–220 grit) repairs damaged or very dull edges. Medium (400–800 grit) sharpens. Fine (1000–3000 grit) refines. Stropping (6000+ grit) polishes to a razor finish.
Angle: Most European knives sharpen at 20–25°. Japanese knives typically sharpen at 15–17°. Use a sharpener that matches your knife's angle or allows adjustment.
Metal removal: All sharpening removes steel. Pull-through models remove the most per pass. Only sharpen when the knife is actually dull — honing before each use maintains the edge longer.
Honing vs. sharpening: Honing steels realign the edge without removing metal. Use a honing rod before each use, sharpen only when honing stops working.
