Why is the Angle Important?

Choosing an angle for sharpening your knife edge is one of the most crucial steps in sharpening. The angle determines how sharp the edge will be, how durable it will be, and how well it will perform in specific tasks. A sharp edge creates the balance between sharpness and durability.

A narrow angle creates a sharper edge but is also more fragile and requires more maintenance. A wider angle creates a more durable edge, but it’s less sharp and requires less maintenance. The angle you choose will depend on the knife you have and your preference. So choose the right angle before sharpening your knife.

Types of Angles:

There are three types of angles used in knife sharpening: acute angles, blunt angles, and convex angles. Here are three following angles you can choose for sharpening a knife-

  • Acute Angle

An acute angle is typically between 10 and 20 degrees which creates a very sharp edge. However, such steep angles are incredibly fragile and require more maintenance. It is used for tasks that require a sharp, delicate edge, such as filleting fish or slicing vegetables.

  • Blunt Angle

A blunt angle is typically between 25 and 30 degrees which creates a more durable edge compared to an acute angle. However, they’re also less sharp and require less maintenance. A blunt angle is used for tasks that require a more robust, durable edge, such as slicing, chopping, and cutting through bone.

  • Convex Angle

A convex angle is a combination of acute and blunt angles, creating a slightly curved edge. Convex angles are commonly used in Japanese knives and are designed to create a balance between sharpness and durability.


Different people have different choices when it comes to selecting an angle for sharpening a knife. The best angle for sharpening your knife depends on the type of knife you are using and the tasks you use your knife for.
