Sharpening a knife is an essential skill for any knife owner, whether you’re a professional chef, an outdoor enthusiast, or a DIY homeowner. However, sharpening a knife can be a daunting task, especially for beginners. One of the most common questions people ask is, “Can you ruin a knife by sharpening it wrong?” The answer is yes, you can ruin a knife by sharpening it incorrectly. In this article, we’ll explore the ways you can damage a knife by sharpening it wrong and provide you with a comprehensive guide on how to sharpen a knife correctly.
Understanding Knife Sharpening
Before we dive into the ways you can ruin a knife by sharpening it wrong, it’s essential to understand the basics of knife sharpening. Knife sharpening is the process of creating a sharp edge on a knife by removing metal from the blade. The goal of sharpening a knife is to create a sharp, durable edge that will last for a long time.
The Importance of Angle
One of the most critical factors in knife sharpening is the angle at which you sharpen the blade. The angle of the sharpening stone or steel determines the sharpness and durability of the edge. If the angle is too shallow, the edge will be too thin and may not hold up well. On the other hand, if the angle is too steep, the edge will be too thick and may not be sharp enough.
Common Sharpening Angles
There are several common sharpening angles, including:
- 20 degrees: This is a good angle for most knives, including chef’s knives and pocket knives.
- 25 degrees: This angle is suitable for thicker blades, such as cleavers and axes.
- 30 degrees: This angle is best for very thick blades, such as machetes and swords.
Ways to Ruin a Knife by Sharpening it Wrong
Now that we’ve covered the basics of knife sharpening, let’s explore the ways you can ruin a knife by sharpening it incorrectly.
Over-Sharpening
One of the most common mistakes people make when sharpening a knife is over-sharpening. Over-sharpening occurs when you sharpen the blade too much, removing too much metal from the edge. This can cause the edge to become too thin and weak, leading to a dull knife that is prone to chipping.
Signs of Over-Sharpening
Here are some signs that you may be over-sharpening your knife:
- The edge becomes too thin and fragile.
- The knife becomes dull quickly.
- The edge starts to chip or crack.
Under-Sharpening
Under-sharpening is the opposite of over-sharpening. It occurs when you don’t sharpen the blade enough, leaving the edge too thick and dull. Under-sharpening can cause the knife to become dull and ineffective, making it difficult to use.
Signs of Under-Sharpening
Here are some signs that you may be under-sharpening your knife:
- The edge remains dull and thick.
- The knife is difficult to use.
- The edge starts to rust or corrode.
Incorrect Angle
Using the incorrect angle when sharpening a knife can cause the edge to become uneven and dull. If the angle is too shallow, the edge will be too thin and may not hold up well. On the other hand, if the angle is too steep, the edge will be too thick and may not be sharp enough.
Signs of Incorrect Angle
Here are some signs that you may be using the incorrect angle:
- The edge becomes uneven and wavy.
- The knife is difficult to sharpen.
- The edge starts to chip or crack.
Using the Wrong Sharpening Tool
Using the wrong sharpening tool can cause damage to the knife and lead to a dull edge. For example, using a sharpening steel on a serrated knife can cause the serrations to become damaged and the edge to become dull.
Common Sharpening Tools
Here are some common sharpening tools:
- Sharpening stones: These are flat stones used to sharpen straight-edge knives.
- Sharpening steels: These are long, thin rods used to hone and realign the edge of a knife.
- Diamond stones: These are flat stones coated with diamond particles used to sharpen very dull knives.
- Electric sharpeners: These are machines that use rotating wheels to sharpen knives.
How to Sharpen a Knife Correctly
Now that we’ve covered the ways you can ruin a knife by sharpening it incorrectly, let’s explore how to sharpen a knife correctly.
Step 1: Choose the Right Sharpening Tool
The first step in sharpening a knife correctly is to choose the right sharpening tool. The type of sharpening tool you use will depend on the type of knife you have and the level of sharpness you need.
Sharpening Stones
Sharpening stones are a good choice for straight-edge knives. They are available in different grits, ranging from coarse to fine.
Sharpening Steels
Sharpening steels are a good choice for honing and realigning the edge of a knife. They are available in different lengths and materials.
Step 2: Prepare the Knife

Cleaning the Knife
Cleaning the knife is an essential step in sharpening a knife correctly. Use a soft cloth and mild soap to clean the knife, paying particular attention to the edge.
Inspecting the Edge
Inspecting the edge is also an essential step in sharpening a knife correctly. Look for any damage or nicks on the edge and remove them before sharpening.
Step 3: Sharpen the Knife
The third step in sharpening a knife correctly is to sharpen the knife. Hold the sharpening tool at the correct angle and draw the knife across the tool in a smooth, even motion.
Sharpening Technique
The sharpening technique you use will depend on the type of sharpening tool you are using. For example, when using a sharpening stone, hold the stone at the correct angle and draw the knife across the stone in a smooth, even motion.
Conclusion
Sharpening a knife can be a daunting task, especially for beginners. However, with the right techniques and tools, you can sharpen a knife correctly and achieve a sharp, durable edge. Remember to always choose the right sharpening tool, prepare the knife, and sharpen the knife at the correct angle.

What are the common mistakes people make when sharpening a knife?
One of the most common mistakes people make when sharpening a knife is applying too much pressure. This can cause the knife to become misshapen, leading to a dull edge. Another mistake is using the wrong sharpening angle, which can result in a knife that is not sharp enough or is unevenly sharpened. Additionally, using a dull sharpening stone or steel can also lead to a poorly sharpened knife.
Other mistakes include sharpening the knife in the wrong direction, not maintaining the correct sharpening angle throughout the process, and not checking the knife’s edge frequently enough. These mistakes can be avoided by taking the time to learn proper sharpening techniques and practicing regularly. It’s also essential to choose the right sharpening tools and to maintain them properly.
How do I choose the right sharpening angle for my knife?
The sharpening angle of a knife depends on its intended use and the type of steel it’s made of. Generally, a sharpening angle of 20 degrees is suitable for most knives, but some knives, such as those used for filleting or skinning, may require a shallower angle of 15-18 degrees. On the other hand, knives used for chopping or cleaving may require a steeper angle of 25-30 degrees.
To determine the best sharpening angle for your knife, consider its intended use and the type of steel it’s made of. If you’re unsure, consult the manufacturer’s instructions or seek advice from a professional. It’s also essential to maintain a consistent sharpening angle throughout the sharpening process to ensure a sharp, even edge.
What is the difference between sharpening and honing a knife?
Sharpening a knife involves removing metal from the blade to create a new edge, while honing a knife involves realigning the existing edge to maintain its sharpness. Sharpening is typically done using a sharpening stone or steel, while honing is done using a honing steel or ceramic hone.
Sharpening is necessary when a knife becomes dull, while honing is a maintenance process that should be done regularly to keep the knife sharp. Honing can help extend the life of a knife by preventing the edge from becoming dull and maintaining its sharpness. However, if a knife is severely dull, sharpening may be necessary before honing.
Can I sharpen a knife with a dull sharpening stone?
No, it’s not recommended to sharpen a knife with a dull sharpening stone. A dull sharpening stone can damage the knife’s edge and make it more difficult to sharpen. A dull stone can also cause the knife to become misshapen, leading to a dull edge.
Instead, use a sharpening stone that is specifically designed for sharpening knives. These stones are made with abrasive materials that help remove metal from the blade and create a sharp edge. If your sharpening stone becomes dull, replace it with a new one or have it resurfaced to maintain its effectiveness.
How often should I sharpen my knife?
The frequency of sharpening a knife depends on its usage and the type of steel it’s made of. If you use your knife frequently, you may need to sharpen it more often. On the other hand, if you only use your knife occasionally, you may only need to sharpen it every few months.
As a general rule, it’s recommended to sharpen a knife when it becomes dull. You can check the knife’s edge by slicing through a piece of paper or a thin piece of wood. If the knife cuts cleanly and easily, it’s sharp. If it tears or catches, it’s time to sharpen it. Regular sharpening can help maintain the knife’s edge and extend its lifespan.
Can I sharpen a serrated knife?
Yes, serrated knives can be sharpened, but it requires a different technique than sharpening a straight-edged knife. Serrated knives have a unique edge with small teeth that need to be maintained to ensure the knife cuts effectively.
To sharpen a serrated knife, use a serrated knife sharpener or a diamond stone specifically designed for sharpening serrated edges. These tools help maintain the teeth on the edge and keep the knife sharp. It’s essential to follow the manufacturer’s instructions for sharpening a serrated knife, as the process can be more complex than sharpening a straight-edged knife.
How do I maintain my sharpening tools?
To maintain your sharpening tools, clean them regularly and store them in a dry place. Sharpening stones should be cleaned with water and a mild soap, while sharpening steels can be cleaned with a dry cloth.
It’s also essential to maintain the sharpening stone’s flatness by resurfacing it regularly. This can be done using a stone dresser or a diamond stone. Additionally, sharpening steels should be replaced every few years or when they become worn out. Regular maintenance can help extend the life of your sharpening tools and ensure they continue to perform effectively.
