The Very Best Way To Sharpen A Knife

In home cooking, all the best easy recipes in the world won't help you if the tool you're using is a blunt knife. Let's delve into the world of knife sharpening and learn how to sharpen that edge.

1. Why Do You Need to Keep Your Knives Sharp?

Whether you're the family handyman, a home cook, or a professional chef, you know that your knife has to be as sharp as possible in order to be as useful as possible. Using dull blades can turn a once satisfying experience into a rough ordeal, affecting not just the aesthetics of your dishes, but also the taste, texture, and even cooking times.

When it comes to cooking, a blunt knife can cause quite a bit of damage. Instead of slicing cleanly through food, a dull blade tears or crushes, disrupting the cell walls and leading to quicker oxidation and degradation of the ingredients. This could affect the visual appeal of your dishes, with ragged and uneven cuts. But more importantly, it may also impact the taste and the overall cooking process. 

A cleanly cut vegetable or piece of meat cooks evenly and presents well on the plate. In contrast, uneven chunks may cook at different rates, potentially messing up your well-planned recipes.

Maintaining your knives sharp brings a wealth of benefits 

Sharp knives are a joy to use. They glide effortlessly through food, making your chopping, dicing, and slicing tasks more efficient and far less tiring. You won't have to struggle with the blade or exert unnecessary force, which not only saves you energy but also improves your cutting techniques. This becomes particularly evident when working with delicate ingredients like herbs or soft vegetables, where a sharp knife can make the difference between precision cuts and a squashed mess.


Safety is another important reason to keep your knives sharp. It may seem unreasonable, but a sharp knife is actually safer than a dull one. Dull knives require you to apply more force when cutting, increasing the likelihood of the blade slipping off the food and causing an accident. Sharp knives, in contrast, need less force, providing better control and precision, reducing the risk of injuries.

Satisfaction and enjoyment

Last but not least, there's the satisfaction and enjoyment factor. Sharp knives can transform food preparation from a chore into a delightful and fulfilling experience. Each clean slice and perfect dice can bring a sense of accomplishment, enhancing the joy of cooking.

According to the test kitchen trials and feedback from both home cooks and professional chefs, sharp knives significantly improve the cooking experience, making kitchen work way more efficient and enjoyable.

So as you embark on the journey of knife sharpening, remember: keeping your knives sharp is not a frivolous endeavor. It's a commitment to better tasting food, safer and more efficient cooking practices, and a more enjoyable kitchen experience. 

2. Types of Knife Sharpeners

 So now you know why you should keep your knives sharp. How do you go about it? Choosing the right knife sharpener can seem overwhelming and scary, with options ranging from budget-friendly manual sharpeners to advanced electric models. 

Manual sharpeners

Manual sharpeners are affordable and compact, ideal for those with limited kitchen space. They usually have multiple slots of varying coarseness to refine your knife's edge and are straightforward to use, pretty popular among home cooks.

Electric sharpeners

Electric sharpeners are quick, convenient, and give consistent results, making them a great choice for frequent knife users. Despite a higher cost, they save time and effort in the long run and have built-in guides ensuring optimal sharpening angles, reducing blade damage risk. According to experts, however, they can take away a bit too much material, so be judicious when using them.

Honing rods

Then there's honing rods. If you're anything like me, you thought honing rods were sharpeners, but that's actually not the case. However, they do maintain the sharpness of an already sharpened blade by realigning the microscopic teeth along the blade's edge. Regular honing can extend the life of your sharp edge and delay the need for full sharpening.

Sharpening stones, or whetstones, offer the most control and are preferred by professional chefs for their precision. They come in different materials and grits for repairing and polishing dull blades, but they require more skill as you manually hold the knife at the correct angle. Sharpening knives with a whetstone can seem intimidating, but you'll eventually grow to love the process; many find it relaxing and therapeutic!

The choice of sharpener depends on your knives, their usage frequency, your budget, and comfort with the sharpening process. Some knives, like serrated ones, need special sharpeners. So it's crucial to research and select a tool fitting your needs. Whether you're a home cook or a professional, understanding sharpeners ensures your kitchen is equipped with sharp cutting tools.

3. Best Way to Sharpen a Knife

Before we dive into the nitty-gritty of the sharpening process, it's important to underscore the difference between honing and sharpening, as these terms are often used interchangeably but represent two distinct techniques. As we mentioned earlier, honing involves realigning the blade's edge and is a maintenance task you'd perform more frequently. Sharpening, on the other hand, involves removing a tiny bit of metal from the blade to create a new, sharp edge. This is done less often but is vital for maintaining a sharp, effective knife.

Now, let's slice into the best way to sharpen your knives with a whetstone:

Preparing the sharpener

If you're using a sharpening stone, the first step is to soak it in water for about 10-15 minutes until bubbles cease to form. The soaking process ensures that the stone won't absorb the metal particles shaved off from your knife during sharpening, preserving the integrity and effectiveness of the stone.

Finding the right angle

This is where an angle guide can prove invaluable, especially for beginners. Most kitchen knives, whether a chef's knife or a utility knife, should be sharpened at approximately a 20-degree angle. This provides an ideal balance between sharpness and durability for common kitchen tasks. Holding the knife at this angle against the sharpener ensures you're shaving the metal at the optimal point, refining the blade's edge for the best performance.

Sharpening process

Once the angle is established, it's time to start the sharpening. Hold onto the knife handle securely with your dominant hand and keep the sharpening stone or tool steady with your nondominant hand. Begin at the base of the knife, nearest the handle. Apply a consistent pressure, and drag the blade down and across the stone or through the sharpener in a smooth, sweeping motion. Imagine you're trying to slice a thin layer off the top of the stone. This pulling motion, often described as "dragging the blade," enables even sharpening across the entire length of the knife edge.

Checking the sharpness

After a few strokes, pause and feel along the edge of the blade for a "burr." This is a tiny lip of metal that curls over as you sharpen one side, indicating that you've sharpened enough on that side. The presence of a burr signifies that it's time to repeat the process on the opposite side of the blade. Once you've formed a burr on both sides, your knife is almost ready. The final step is to remove the burrs by lightly dragging the blade over the sharpener a couple more times.

Electric knife sharpening and manual knife sharpeners follow a different process that is much more straightforward, thus requiring less skill (which is, unfortunately, reflected in the results you will get from those types of sharpeners).

Remember: learning how to sharpen a knife with a stone takes time and patience, but it's an incredibly rewarding skill. Each session will help you develop a feel for the knife and the whetstone, enabling you to achieve better and more consistent results. It may seem a bit daunting at first, especially with various knife sets requiring different techniques, but practice makes perfect! Before long, you'll be wielding your sharpening tool like a professional, breathing new life into dull blades and taking your cooking experience to a whole new level.

Learning how to properly sharpen your knives, like mastering any cooking techniques, involves more than just knowing the process. Here are some quick handy tips that can help you sharpen your skills and hone your knives like a professional chef:

Prioritize safety

Always maintain a safe distance from the blade's edge during sharpening to avoid cuts. Stay aware of your fingers' positions near sharp edges.

Stabilize your tools

An even sharpening process requires a stable tool. For a sharpening stone, use a nonslip base; for manual or electric sharpeners, position on a flat surface.

Choose the correct grit

For very dull knives, start with a coarse grit for reshaping the blade, then switch to a fine grit for refinement and polish.

Hone regularly

Post-sharpening, hone your knife to realign microscopic teeth along the blade's edge, extending the sharpness.

Clean after sharpening

Remove any metal particles left from sharpening by cleaning your knife thoroughly, preventing blade dulling and food contamination.
