Honing vs Sharpening — What Is the Difference?

  • Honing (honing rod/steel): Realigns the microscopic edge of the blade that folds over with use. Does not remove metal. Should be done before every use or weekly. Takes 30 seconds. Most knife dullness is solved by honing.
  • Sharpening (whetstone, pull-through sharpener): Removes metal from the blade to restore a proper edge. Done when honing no longer restores sharpness — typically 2–4 times per year for home use.

Method 1: Honing Rod (Regular Maintenance)

  1. 1

    Hold the rod vertically on a cutting board

    Place the tip of the honing rod on the cutting board. Hold it steady with one hand.

  2. 2

    Draw the knife down at 15–20 degrees

    Place the heel of the knife against the top of the rod at roughly 15–20 degrees (a slightly acute angle — thinner than you might think). Draw the knife downward along the rod while simultaneously pulling it toward you, so the full length of the blade contacts the rod in one stroke. Apply light to medium pressure.

  3. 3

    Alternate sides, 5–10 strokes each

    Alternate between sides (left side, right side) for 5–10 strokes each. The knife should feel noticeably sharper after a good honing session.

Method 2: Pull-Through Sharpener (Easy, Good for Most Home Cooks)

Place the sharpener on a non-slip surface. Draw the knife through the coarse slot first (for very dull knives), then the fine slot, using light pressure and pulling the blade toward you heel-to-tip. 3–5 passes per slot. Pull-through sharpeners are quick and consistent but remove more metal than necessary if used too frequently. Use only when honing stops working.

Method 3: Whetstone (Best Results)

A whetstone (sharpening stone) produces the best edge but requires practice. Soak the stone in water for 5 minutes. Hold the knife at 15–20 degrees to the stone. Push the knife forward and across the stone heel-to-tip on the forward stroke. 10–15 strokes per side on the coarse grit, then repeat on the fine grit. Finish with 5 strokes on a honing rod. YouTube tutorials specific to your knife type are very helpful for learning whetstone technique.

Testing sharpnessPaper test: hold a sheet of printer paper vertically and slice down through it — a sharp knife cuts cleanly with no tearing. Tomato test: a sharp knife cuts through tomato skin without pressure. Fingernail test: carefully hold the blade at 45 degrees to your fingernail — a sharp knife catches and resists sliding; a dull one slides off.

Frequently Asked Questions

Hone before every use (or at least weekly). Sharpen (remove metal) 2–4 times per year for a home cook using knives daily. Knives used very frequently or on hard ingredients (squash, bones) need sharpening more often. The best indicator is whether the knife cuts effortlessly — never let knives get so dull you need significant force to cut, as this is both inefficient and dangerous.
Standard sharpeners and honing rods do not work on ceramic knives — diamond sharpeners are required as ceramic is extremely hard. Ceramic knives hold their edge for much longer than steel but when they do dull, they are best sent to a professional sharpener with the right diamond tools. They are also very brittle and chip if dropped or used on hard foods.
