Exploring Knife Sharpening Methods
While several methods exist for sharpening knives, using a whetstone provides the most control and preserves the life of your blades.
- Electric Sharpeners: While convenient, electric sharpeners can remove excessive material from the blade, shortening its lifespan and potentially damaging the balance. They also may not provide the keenest edge compared to other methods.
- Professional Sharpening Services: A good option if you lack the time or confidence to sharpen your knives yourself. However, the cost can add up, especially if you sharpen your knives frequently. Also, some professionals might use grinding stones that remove more material than necessary.
- Sharpening Stones (Whetstones): This is the preferred method for achieving the sharpest edge while minimizing material removal. It requires practice but offers superior results and fosters a deeper connection with your knives.
Essential Whetstone Shopping and Maintenance Tips
When selecting a whetstone, consider size and grit. A larger stone (at least 2.5 inches wide by 8 inches long and 1 inch thick) offers a more stable sharpening surface. Grit refers to the coarseness of the stone, ranging from around 100 to 10,000+. Lower numbers indicate coarser grits, which remove more material quickly.
Recommendations:
- Medium-grit stone (around 800-1200): For repairing damaged edges or initial sharpening. A versatile grit for general knife maintenance is between 1,000 and 1,200.
- Fine-grit stone (2000+): For refining the edge and achieving a razor-sharp finish.
- Ultra-fine grit stone (8000+): While providing a mirror-like polish, the cutting performance difference may be negligible for most home cooks.
- Stone Fixer/Flattening Stone: Essential for maintaining a flat, even surface on your whetstones.

Maintenance:
- Dry your stones thoroughly after each use.
- Store them wrapped in a kitchen towel in a dry, grease-free environment.
- Hone your knife on a steel before each use to maintain edge alignment.
Step-by-Step Guide: How to Use a Whetstone
Follow these steps to sharpen your knives effectively using a whetstone:
Step 1: Soak Your Stones
Submerge waterstones in water for at least 45 minutes before use. Fully saturated stones prevent the blade from catching and ensure even sharpening. Soak your stone fixer as well.
:max_bytes(150000):strip_icc()/optaboutcomcoeusresourcescontent_migration__serious_eatsseriouseats.comimages20100423-sharpening20-2002-33e38a77decc49cd93c7b9e1c32a73fc.jpg)
Whetstones submerged in water to ensure proper saturation before use.
Step 2: Set Up Your Station
Place the whetstone on a damp towel over a cutting board to prevent it from slipping. Keep a container of water nearby to re-moisten the stone during sharpening. Position the stone with the short end parallel to the counter edge.
:max_bytes(150000):strip_icc()/optaboutcomcoeusresourcescontent_migration__serious_eatsseriouseats.comimages20100423-sharpening20-2003-6d1c60d4aaf94d9f9502515ac054452d.jpg)
A whetstone placed securely on a towel-covered cutting board for stability.
Step 3: Begin First Stroke
Using the lower-grit stone, place the heel of the knife blade on the far edge of the stone at a 15- to 20-degree angle. Hold the blade firmly with both hands.
:max_bytes(150000):strip_icc()/optaboutcomcoeusresourcescontent_migration__serious_eatsseriouseats.comimages20100423-sharpening20-2004-aba6e6fa129844a7a106fa006eb98c3d.jpg)
Correct hand placement and blade angle for the initial sharpening stroke on a whetstone.
Step 4: Maintain Angle
Maintaining a consistent 15- to 20-degree angle is crucial. Use an angle guide if needed. Apply firm, gentle pressure, allowing the blade to glide smoothly.
:max_bytes(150000):strip_icc()/optaboutcomcoeusresourcescontent_migration__serious_eatsseriouseats.comimages20100423-sharpening20-2005-c34b2ff5be7a4fb080189e51067d12cc.jpg)
Maintaining the correct angle is essential for effective knife sharpening.
Step 5: Finish Stroke and Repeat
Each stroke should end with the tip of the knife touching the bottom of the stone. Lift the knife, reset the heel at the top, and repeat the motion.

Repeating the sharpening stroke ensures consistent edge refinement.
Step 6: Look for Silty Water
A thin film of silty water will form on the stone and blade. This abrasive liquid removes material from the edge, sharpening the knife.
:max_bytes(150000):strip_icc()/optaboutcomcoeusresourcescontent_migration__serious_eatsseriouseats.comimages20100423-sharpening20-2007-740ca3ca72b744f1b0d9906c2d7b10f3.jpg)
Silty water indicates the removal of metal and the sharpening process in action.
Step 7: Check for Burr
After several strokes, a tiny burr will form on the opposite side of the blade. Test by gently pulling the blade backwards across your thumbnail. If a burr has formed, switch to the other side.
:max_bytes(150000):strip_icc()/optaboutcomcoeusresourcescontent_migration__serious_eatsseriouseats.comimages20100423-sharpening20-2008-86e8b741375f429680e79574555e38a2.jpg)
Checking for a burr on the blade edge indicates it’s time to sharpen the other side.
Step 8: Start Sharpening Second Side
Place the heel of the blade near the base of the stone, maintaining a 15- to 20-degree angle. Gently push the blade away from you while dragging it across the stone towards the tip.
:max_bytes(150000):strip_icc()/optaboutcomcoeusresourcescontent_migration__serious_eatsseriouseats.comimages20100423-sharpening20-2009-70f22d6a6cda4986892e42e002c484e9.jpg)
Sharpening the second side of the blade requires a similar technique but pushing away.
Step 9: Finish Second Side
End the stroke with the tip of the blade against the top edge of the stone, maintaining the angle. Moisten the stone if it dries out. Repeat the same number of strokes used to form the burr on the first side.
:max_bytes(150000):strip_icc()/optaboutcomcoeusresourcescontent_migration__serious_eatsseriouseats.comimges20100423-sharpening20-2010-29d0c2c393ef417190074a6cd6f23732.jpg)
Completing the sharpening stroke on the second side ensures even edge refinement.
Step 10: Switch Stones
Move to the finer-grit stone and repeat steps three through nine.
Step 11: Fix Stones
Use a stone fixer to flatten any grooves that develop on your whetstones. Place the fixer flat against the stone and grind back and forth to create a new, flat surface.
:max_bytes(150000):strip_icc()/optaboutcomcoeusresourcescontent_migration__serious_eatsseriouseats.comimages20100423-sharpening20-2011-1c27920fe0db43feadc0144c7007f441.jpg)
Using a stone fixer to maintain a flat and even sharpening surface.
Step 12: Clean Up
Use a dedicated towel to clean the stones, as the grit is difficult to remove. Allow the stones to dry completely before storing.

Proper cleanup and storage of whetstones after sharpening.
Step 13: Hone and Test Your Blade
Hone your blade on a honing steel to realign the edge. Test the sharpness by slicing a vegetable, like a tomato or onion. A sharp knife should glide through with minimal resistance.
