If you’ve ever wondered why some knives glide through food while others feel like they’re fighting you, there’s a good chance it comes down to one thing: the knife sharpening angle.
It’s not just a technical detail, it’s what determines how sharp your knife feels, how long it holds that edge, and how well it handles different jobs in the kitchen. Get it right, and your knife does the work for you. Get it wrong, and even a high-quality blade can feel average.
Let’s break it down in a straightforward way.
What Is a Knife Sharpening Angle?
The knife sharpening angle is the angle at which you hold your blade against a sharpening stone or system.
Most knives are double-bevel, meaning both sides are sharpened. So if you sharpen each side at 20 degrees, you end up with a total edge angle of 40 degrees.
There are also single-bevel knives, where only one side is sharpened while the other remains flat. These are more specialised and commonly found in traditional Japanese knives, but for most kitchens in Australia, you’ll be dealing with double-bevel blades.
Why the Knife Sharpening Angle Matters
Choosing the right knife sharpening angle is all about balance:
-
Lower angle = sharper edge
Cuts effortlessly but can chip or wear faster -
Higher angle = stronger edge
More durable but not quite as sharp
Think of it like this—if you’re slicing tomatoes or trimming meat, you want a fine edge. If you’re hacking through tougher ingredients or doing rougher work, you need something with a bit more strength behind it.
Understanding Steel: Hardness vs Toughness
Before you settle on an angle, it’s worth knowing that not all knives behave the same. The type of steel plays a big role.
-
Harder steel
Holds an edge longer
Can handle lower sharpening angles
More prone to chipping if mistreated -
Softer steel
Tougher and more forgiving
Better suited to wider angles
Needs sharpening more often
It’s always a trade-off. A super hard knife at a very low angle might be razor sharp—but it won’t forgive heavy-handed use.
Common Knife Sharpening Angles (And When to Use Them)
10°–15°: Razor Sharp, But Delicate
This is a very fine knife sharpening angle.
- Best for: precision slicing, soft foods
- Common in: high-end Japanese knives
- Downside: chips easily if used for anything heavy
This range is brilliant for clean, effortless cuts—but you’ve got to treat the knife with care.
15°–17°: High Performance Edge
A popular choice for premium kitchen knives.
- Best for: vegetables, boneless meats
- Offers: excellent sharpness with reasonable durability
This is where performance really starts to shine without becoming overly fragile.
17°–20°: The Everyday Sweet Spot
If you’re looking for a reliable, all-round knife sharpening angle, this is it.
- Best for: general kitchen use
- Common in: Western chef knives
- Balanced sharpness and durability
For most home cooks and even plenty of pros, this range does the job beautifully.
20°–25°: Tougher and More Forgiving
A slightly wider angle that adds durability.
- Best for: heavier cutting tasks
- Good for: utility knives or multi-purpose use
You lose a bit of that razor-like feel, but gain a lot in toughness.
25°–30°: Built for Hard Work
This range is all about strength.
- Best for: rough use, hard materials
- Common in: cleavers, outdoor knives
Not the sharpest edge, but it’ll stand up to serious work without failing.
Choosing the Right Knife Sharpening Angle
There’s no one perfect angle—it depends on how you use your knife.
Ask yourself:
- What am I cutting most often?
- Do I prioritise sharpness or durability?
- Am I careful with my knives, or do they cop a bit of abuse?
If you’re unsure, starting around 17°–20° per side is a safe and effective choice. From there, you can adjust based on how your knife performs.
Getting Consistent Results
One of the biggest challenges with sharpening isn’t knowing the angle—it’s holding it consistently.
That’s where the right tools make a massive difference.
If you’re serious about improving your edge, it’s worth using a proper sharpening system rather than guessing by hand. At Chef Supply Co., we stock a range of options to suit different skill levels, from beginners to experienced users.

Using a guided sharpener or a quality stone setup helps you maintain a consistent knife sharpening angle, which is the key to getting a clean, long-lasting edge.
Final Thoughts
Understanding the knife sharpening angle is one of the simplest ways to level up your knives. It’s not just about making them sharp, it’s about making them work properly for what you need.
A finer angle gives you that effortless slicing feel, while a wider angle gives you confidence when things get a bit tougher.
Start with a solid middle ground, pay attention to how your knife performs, and tweak from there. Once you get the hang of it, you’ll wonder how you ever put up with a dull blade.
At the end of the day, a well-sharpened knife doesn’t just make cooking easier—it makes it a whole lot more enjoyable.
