So, you’ve got a kitchen knife in hand, and you’ve probably used it hundreds of times—slicing through veggies, maybe a roast or two, without giving a second thought to what makes it work so well. But then, one day, you notice it’s not slicing through that tomato as smoothly as it used to. Maybe it’s time to sharpen it? And that’s when it hits you: what degree is the average kitchen knife supposed to be sharpened to?
Seems like a simple enough question, right? But once you start digging into it, the answer isn’t as straightforward as you'd think. Trust me, I went down this rabbit hole myself when I bought my first sharpening stone. And yeah, there’s a lot more to it than just "sharp" or "dull." Turns out, the angle of your knife’s edge—measured in degrees—is key to how well it performs. But before we get into all the nitty-gritty of angles and sharpness, let’s back up a little.
What Does "Degree" Mean When We Talk About Kitchen Knives?
First off, when people talk about the "degree" of a kitchen knife, they’re referring to the angle at which the blade is sharpened. You see, a knife isn’t just a single flat edge; it’s actually two surfaces that come together at an angle to form the sharp part. This angle can make all the difference when it comes to how well your knife slices through food, how easy it is to control, and even how often it needs to be sharpened.
The degree of a knife’s edge is measured from the centerline of the blade to one side of the edge. So, if someone says your knife has a 20-degree angle, it means that one side of the blade is sharpened at a 20-degree angle from the centerline.
Sounds simple enough, but the truth is, there’s no one-size-fits-all answer here. Different knives—and even different types of food—might require different angles. Who knew?
The Average Kitchen Knife Angle: What’s "Normal"?
Okay, let’s get to the heart of it. What degree is the average kitchen knife sharpened to? Well, most standard kitchen knives—those trusty chef's knives, paring knives, and utility knives you reach for every day—are usually sharpened to somewhere between 15 and 20 degrees per side. That means the total edge angle (if you think of the edge as a V) is between 30 and 40 degrees.
So, why this specific range? It's about finding a balance. An edge angled at 15 degrees is thinner, sharper. It easily handles gentle jobs like slicing tomatoes or preparing fish. But, and here's the downside, a sharper blade can be delicate. It might get blunt fast or even break when used on hard items like butternut squash or chicken with bones.
On the other hand, a 20-degree angled knife is somewhat more sturdy. Though it may lack the slick, razor-like precision of a sharper edge, it's more enduring, especially when used for heavy jobs like chopping, dicing, or slicing through harder stuff. Therefore, most people cooking at home find a sweet spot between 15 to 20 degrees. It's sharp enough for precision tasks and robust enough to withstand everyday use.
But Wait, What About Japanese Knives?
Ah, the plot thickens. If you’ve ever bought or ogled a Japanese kitchen knife, you might have noticed something different about them. Traditional Japanese knives, like santoku or gyuto knives, are often sharpened to a much finer angle—sometimes as low as 12 to 15 degrees per side.
How come? It's all about their traditional use. Usually, Japanese knives are meant for precise tasks like sushi fish slicing or detailed chopping of veggies. They're crafted from hard steel, which sustains a sharp edge longer.
Yet—there's a catch—they are a tad more fragile. So, if you're expecting to slice through a hard object such as a whole chicken or a chunky vegetable, do be careful. These knives are quite sharp; however, they lack brute power.
Therefore, if in your kitchen you have a blend of Western-styled and Japanese knives, they may need to be sharpened at unique angles. Western knives, having chunkier blades, can withstand a 20-degree angle, while Japanese knives flourish at sharper ones.
How to Choose the Right Degree for Your Knife
Now that you know the basics, you might be wondering, How do I know what degree I should sharpen my knife to? And yeah, that can be a bit confusing. But it doesn’t have to be. Here are a few factors to think about:
What are you using the knife for? If you’re doing a lot of delicate slicing, you might prefer a sharper angle (closer to 15 degrees). But if you’re chopping, dicing, or cutting through tough ingredients, a sturdier edge (around 20 degrees) will give you more durability.
What kind of knife is it? As we mentioned, Japanese knives tend to be sharper and more delicate, while Western-style knives often have a more durable edge. Stick to the range that works best for the type of knife you have.
What kind of steel is your knife made from? Harder steels can hold a finer edge, but they’re more brittle. Softer steels might need a slightly wider angle to stay durable. If you're not sure what your knife is made from, checking the manufacturer's guidelines is always a good place to start.
How Do You Sharpen to the Right Degree?
Here’s where it gets tricky—knowing how to sharpen a knife to a specific degree is half the battle. If you’ve ever tried to sharpen a knife on your own, you probably know that it’s easier said than done. Holding the knife at a consistent angle takes some practice. So, how do you get it right?
There are a few options:
Manual Sharpening Stones (Whetstones): These give you full control over the sharpening angle, but it can be tricky to hold the knife at the correct degree without some practice. Patience is key here. You’ll often find tutorials that show you how to maintain the right angle (some people even use coins as a guide).
Sharpening Guides: These handy little gadgets clip onto your knife and help you maintain the right angle while sharpening. They’re especially helpful if you’re using a whetstone and want to make sure you’re not all over the place with your angle.
Electric Sharpeners: Many electric sharpeners come pre-set with sharpening angles, usually between 15 and 20 degrees. They make the process quick and easy but don’t always give you the option to customize the angle beyond those presets.
The Bottom Line: What Degree is Right for You?
What's the key point? The normal kitchen knife gets honed from 15 to 20 degrees each side. But, its usage influences this. If you need high precision, go for a sharper edge (around 15 degrees). Daily uses like chopping and dicing? A 20-degree angle is ideal. Remember, different knives, like the Japanese and Western styles, need custom sharpening.
However, the degree isn't everything. A good handle on knife care, like honing regularly and storing it properly, also counts. Now that you understand this, it might be time to work on your sharpening stone. Maybe you can get your knife to slice those tomatoes smoothly again.
Or, if you're like me, you might just keep wondering - am I maintaining the right angle as I sharpen? Well, nobody is perfect!
