How To Sharpen A Knife With A Sharpening Stone?

Sharpening a knife using a sharpening stone is an essential tool for the kitchen. A sharp knife can make food preparation easier and more efficient, ensuring that your meals are always cooked to perfection. A sharp knife is also safe to use.

Types Of Sharpening Stones

There are three main types of sharpening stones:

  • Natural Stones: These stones are quarried from natural sources and are known for their durability and effectiveness. They tend to be more expensive than synthetic stones.
  • Synthetic Stones: These are man-made stones of abrasive materials such as aluminum oxide, silicon carbide, or ceramic. They are widely available, affordable, and come in various grits.
  • Diamond Stones: These are metal plates coated with diamond particles. They offer fast material removal and long-lasting durability but can be pricey.

How To Sharpen A Knife With A Sharpening Stone?

Step 1: Place the sharpening stone onto a secure and flat surface. Make sure it won’t move around easily while you are using it.

Step 2: Soak the sharpening stone with water for about 5 minutes or until bubbles form on its surface. This will help create a slurry of fine particles to help polish the blade.

Step 3: Hold the blade of your knife at a 15-20 degree angle concerning the stone and begin sharpening by dragging it across the stone in an arc motion, starting from the hilt towards where the blade meets its tip. Remember to keep the same angle while moving across.

Step 4: After several strokes, check the sharpness of your knife by gently running your finger across the blade to see if it catches at all. If so, continue with step 3 and repeat until you have achieved the desired sharpness.

Step 5: Clean your knife and stone off with a damp cloth and apply a light coat of oil onto the blade. This will help to protect it from rust and extend its life.

Step 6: Store your knife properly with a cover or sheath and store the stone in a dry place away from direct sunlight. This will ensure maximum durability and sharpness for longer periods of time.

Signs That Your Knife Needs Sharpening

1. Difficulty in Cutting: One of the most apparent signs that your knife needs sharpening is when cutting through food or materials becomes difficult. A sharp knife should slice with ease, requiring minimal effort. If you exert more force or struggle to make clean cuts, it’s time to sharpen your knife.

2. Frayed or Torn Edges: A dull knife often creates frayed or torn edges instead of clean, smooth cuts. If you notice the edges of the food or material you’re cutting are ragged or uneven, your knife likely needs sharpening.

3. Slipping: A dull blade can be more prone to slipping off the surface of the item you’re trying to cut. This makes cutting tasks more difficult and can also be dangerous, as the knife may slip unexpectedly and cause injury.

4. Inconsistent Cutting Performance: If your knife performs well on some cutting tasks but struggles with others, it could be a sign that the blade needs sharpening. A well-sharpened knife should provide consistent performance across a range of tasks.

5. Squashing Soft Foods: When slicing soft foods like tomatoes or bread, a dull knife may squash or compress the food rather than cutting cleanly through it. If your knife squashes soft foods instead of slicing them, it’s time to sharpen the blade.

6. Increased Cutting Time: A dull knife will take longer to cut through materials, leading to increased cutting time and reduced efficiency. If you notice that tasks are taking longer than usual, it could be a sign that your knife needs sharpening.

7. Uneven Blade Edge: Inspect the edge of your knife for any nicks, chips, or unevenness. These imperfections can affect the performance of your knife and are a sign that it’s time for sharpening.

Tips For Maintaining Sharpening Stone

  • Keep your sharpening stone lubricated: Use oil or water to keep the stone from getting clogged with metal shavings, ensuring that it continues to perform effectively.
  • Clean the stone regularly: After each use, clean the sharpening stone with a soft brush to remove any leftover debris and keep it performing optimally.
  • Store the stone in a dry place: Keep your sharpening stone out of direct sunlight and in a cool, dry area to prevent damage.
  • Sharpen both sides of the blade equally: Make sure to sharpen both sides of your knife’s blade for consistency and even wear.
  • Change the angle of your blade as you sharpen: As you work on sharpening a knife, it’s important to adjust the angle of the blade slightly over time to ensure an even edge.

Following these tips lets you get the most out of your sharpening stone and keep your knives in top condition. With regular maintenance and proper use, your sharpening stone can keep your knives sharp for years.


How often should I sharpen my knives?

The frequency depends on how often you use your knives and your cutting tasks. Generally, it would help to sharpen your knives when you notice decreased performance or difficulty cutting through food.

Can I use a sharpening stone on serrated knives?

Sharpening serrated knives requires a different technique and specialized tools, such as a serrated knife sharpener or tapered sharpening rod.

Do I need to use water or oil with diamond stones?

Diamond stones don’t require water or oil, but using a lubricant can help reduce friction and extend the life of the stone.

What are sharpened stones used for?

Sharpening stones hone a blade, giving it a sharper and more precise edge. These stones can also be used to repair worn blades or restore their original condition.

Are whetstones hard to use?

Not necessarily! While sharpening a knife on a whetstone might take some practice and patience to master, it is not hard to do. It would help if you started by soaking the stone in water for 10-15 minutes before use and then placing the stone on a flat surface for stability before use.
