How to Sharpen a Curved Knife in Different Methods?

Curved knives come in all shapes and sizes, but each of them needs to be sharpened. Sharpen a curved knife safer than dull ones because you don't have to force them through your food or use more pressure than necessary. And depending on the type of knife, sharper knives could also make cooking easier.

There are a few ways on how to sharpening a curved knife that you can sharpen your knife at home if you're not too concerned about spending money.

Types of Curved Knives

Types of Curved Knives

Types of curved knives include French curve, flexible curve, hunting blade, and fillet. The French curve knife is perfect for scooping or serving.

The flexible curve can be used for chopping food on the board. It has an edge that will not dull as quickly as other knives.

The hunting blade is used to cut the meat off of the bone or cut large game like deer or moose. Finally, the fillet knife is perfect for slicing fish.

How to Sharpen a Curved Knife is Divided into Two Methods

Generally, there are two methods to sharpening your knives at home. One is manual and the second is electric.

01. Manual Sharpening Method

Step 01: Secure the knife in the vice. If you're working on a flat surface, it's best to stick to your stone abrasive for this step.

Step 02: Make sure not to put any pressure on the blade when sharpening. It might take longer especially if you have serrated blades but make sure not to apply heavy pressure or else you might risk chipping or damaging your blade.

Step 03: Use your whetstone with water, oil, or no matter what lubricant is recommended by knife sharpening services. Make sure to sharpen the angled side of the blade first before repeating it on the other side.

Step 04: Rinse your knife with water and wipe it down with a towel.

There are various kits available like Spyderco Sharpmaker or sharpening rod, which you could use to sharpen your knives manually.

02. Electric Sharpening Method

Step 01: If possible, secure the electric knife sharpener on a flat surface for this step.

Step 02: Put your blade in the slot where it's marked as for what kind of blade you have, usually a serrated or a fine blade.

For an electric sharpener, make sure that both sides of the blade are covered by the edges before turning on your machine.

Step 03: Sharpen both sides of the blade on a medium setting at first before going on a higher speed on the opposite side.

Step 04: Turn off the machine and wipe the blade with a towel.

If you have the budget, taking advantage of knife sharpening tool services is a worthwhile investment. And if not, using either an electric or manual sharpener can help keep your knives as efficient and effective as ever.

A sharpening stone is another method, but sturdy stones are generally used to sharpening serrated knives, paring knife, filleting knife and they're not recommended for karambit knife ones.

Types Curved of Knife Blade

Types Curved of Knife Blade

Curved blade knives are usually made out of stainless steel or high carbon steel.

i) Serrated Blade

Serrated blades are common in bread knives because their teeth can easily cut through sturdier bread crusts.

ii) Fine Blade

The fine blade is used for meats and fish. It's much more delicate than a serrated one to avoid tearing the meat apart instead of slicing it.

iii) Hunting Blade

Hunting blade knives are used to cut the meat off of the bone for gutting. They're not particularly common but can be useful if you hunt often.

Beginners Caution's

If you're a beginner, it's important to take care while sharpening your knives.

Step 01: Hold the knife at a 20-degree angle for both sides of the knife blade.

Step 02: Follow through with smooth strokes on each side before moving onto another area on the blade.

Step 03: Be especially careful when dealing with serrated blades because, on the last few strokes, they can easily chip or break.

Applications of Curved Knife

01. Kitchen

Depending on the size and shape of your blade, using a curved kitchen knife can make preparing food faster and easier.

Chopping vegetables like potatoes or carrots is no longer tedious when you use a French curve knife because it perfectly scoops them into cubes that are uniform in size. You can also easily cut leafy vegetables like kale with the same knife.

Straight blades are used for simple slicing and cutting jobs. They're the most common knives in a kitchen and for good reason; they can handle all sorts of food easily and efficiently.

02. Outdoor

It's easy to make kindling when you use a curved boning knife to cut small branches.

And while cutting through the skin of a game like a deer, moose, or elk is easier with a hunting blade, using it to slice vegetables on your outdoor adventure is also more efficient than if you used an ordinary pocket knife.

And a serrated knife is perfect for slicing through the skin of a small game.

03. Setting up a Survival Kit

You should include serrated knives in your survival kit because they can cut through the tough skin of the game, but also be used to prepare to kindle.

When Should You Sharpen a Curved Knife?

When Should You Sharpen a Curved Knife

You'll need to sharpen your curved blade knives the most when they become dull. But there are also other times when it's important to sharpen them like when:

The knife is difficult to control because it keeps slipping off of whatever you're trying to cut. The curved blade doesn't seem sharp anymore even if you've used it a few times.

The blade is getting shorter over time, making it difficult to cut through anything larger than a grapefruit with ease.


No matter how you choose to get your knives sharpened, it's imperative that they're always kept in tip-top shape. Sharpening steel rods and knife sharpeners can both help keep your knives as sharp as the day you bought them.

Whether you choose to sharpen your knives at home or take them for professional sharpening services, it's important that they're always kept in good condition.
