How to Sharpen a Knife at Home: Manual Methods

Quick take: A sharp knife is safer than a dull one. Learn whetstone sharpening or simple steel honing for kitchen maintenance.

Whetstone method: Soak a 1000-grit stone in water for 15-30 minutes. Hold the knife at a 15-20-degree angle. Push the blade across the stone in sweeping arcs, 10-15 strokes per side. Progress to 3000-grit for polishing.

The steel (honing): Hold the steel vertically. Place heel of blade against steel at 15-20-degree angle. Draw down and across, alternating sides, 5-10 strokes per side.

Testing sharpness: Try slicing through printer paper cleanly. Or cut a tomato—sharp knives glide through without crushing.

Hone weekly, sharpen monthly for home cooks.

Frequently Asked Questions

What's the difference between honing and sharpening?

Honing (using a steel) straightens the existing edge without removing material. Sharpening (using a whetstone) actually removes metal to create a new edge. Hone weekly, sharpen monthly.

What angle should you sharpen kitchen knives?

Hold the knife at a 15-20 degree angle against the whetstone. Japanese knives typically use 15 degrees, while Western knives use 20 degrees.

How do you test if a knife is sharp?

Try slicing through printer paper cleanly — a sharp knife cuts without tearing. Or cut a tomato — sharp knives glide through the skin without crushing.
