A Santoku knife is a must-have in every kitchen. Its short, sharp blade makes slicing, dicing, and mincing easy. But even the best blade gets dull with use. Knowing how to sharpen a Santoku knife at home keeps it performing like new.
Why You Should Sharpen Your Santoku Knife
A dull knife is not only slow it’s unsafe. It can slip and cause accidents. A sharp blade slices clean and fast, keeping you safe and efficient.
Sharpening also protects the knife. Whether you use a Sabatier, Farberware, or a premium Japanese knife set, regular care extends its life.
Tools You’ll Need
Before you begin, gather the right tools:
-
A sharpening stone (also called a whetstone)
-
A clean cloth
-
Water
-
A towel or non-slip mat
-
A honing rod (optional for regular upkeep)
Avoid using electric sharpeners on Santoku knives. They can damage the thin edge.
Understand Your Santoku Knife
Most Santoku knives range from 5 to 7 inches in length. They’re made from stainless steel and have a thinner blade than a traditional chef’s knife.
The blade angle is key. Santoku knives typically have a 12–15 degree angle on each side. This angle helps the knife stay sharp longer and cut cleanly.
Step-by-Step Guide to Sharpen a Santoku Knife
Let’s walk through the process:
1. Soak the Sharpening Stone
Place your sharpening stone in water for 10–15 minutes. This helps create a smooth surface and removes debris while sharpening.
2. Find the Right Blade Angle
Hold the blade at about 15 degrees to the stone. You can use a sharpening guide if you’re unsure. Getting the angle right is key to a sharp edge.
3. Sharpen One Side First
Place the knife edge against the coarse side of the stone. Start at the heel and drag to the tip. Use smooth, steady strokes. Do 10–15 passes per side.
4. Flip and Repeat
Turn the knife over. Keep the same angle. Repeat the same number of strokes on this side to keep the blade balanced.
5. Switch to the Fine Grit Side
After both sides are sharpened on the coarse grit, flip the stone to the fine grit side. Repeat the same motions. This polishes the edge for a smooth cut.
6. Rinse and Dry
Rinse the knife in water. Wipe with a soft cloth. Never put a sharpened knife in the dishwasher. Even dishwasher-safe labels don’t protect the edge. Hand washing is best.
Common Mistakes to Avoid
Sharpening seems simple, but a few mistakes can ruin your blade:
-
Using the wrong angle
-
Pressing too hard
-
Skipping the fine grit
-
Not cleaning the stone
Always stay focused and gentle.
Maintenance Tips
Keep your kitchen knife sharp with good habits:
-
Hone weekly using a rod
-
Store in a knife block or on a magnetic strip
-
Wash by hand after every use
-
Never cut on glass or stone boards
Proper care means you sharpen less often.

Frequently Asked Questions (FAQ)
1. What is the best angle to sharpen a Santoku knife?
Santoku knives are best sharpened at a 12–15 degree angle on each side. This shallow angle keeps the edge razor-sharp and suitable for fine slicing.
2. Can I sharpen a Santoku knife with a regular sharpener?
It’s not recommended. Use a sharpening stone (whetstone) for better control. Electric sharpeners may damage the thin edge of the blade.
3. How often should I sharpen my Santoku knife?
If used daily, sharpen every 2–3 months. For maintenance, use a honing rod weekly to realign the blade and reduce the need for full sharpening.
4. Is a Santoku knife better than a Chef’s knife?
It depends on your cooking style. A Chef’s knife is great for rocking motions, while a Santoku excels at precise slicing and chopping. Many cooks use both.
5. Can I use a sharpening stone on a Farberware or Sabatier knife?
Yes. Both Farberware and Sabatier stainless steel blades can be sharpened with a whetstone. Just follow the correct blade angle and steps.
