The diamond knife sharpener is a device that is designed to quickly and efficiently sharpen any kitchen knives. It contains a diamond-coated steel rod and many other attachments for different sizes and styles of blades. This makes it a great tool for everyday maintenance, as well as occasional touch-ups on very dull knives. In this guide, we’ll discuss how to use the diamond knife sharpener correctly to get the best results.


1) Start by mounting the sharpener on a flat surface with its handle facing away from you. Make sure that you are in a well-lit area so you can clearly see what you’re doing.

2) Now take a look at your knife – hold it firmly in one hand and identify the dull side of the blade. Most knives have two beveled sides – one coarse and one fine – but if yours has only one side then make sure to decide which angle (15 or 20 degrees) you want for each bevel before starting.

3) Place the blunt end of your knife against the base of the diamond rod at an angle corresponding to your desired bevel. Gently move it back and forth while applying light pressure – don’t push too hard or you risk damaging the blade’s edge or missing spots!

4) Switch angles after every few passes until both sides of the blade are equally sharpened then stop. Any more than this may actually damage your blade instead of sharpening it further, so take care near perfection.

5) Once finished, move onto cleaning up! Use either a damp cloth or very lightly press wood against wood to wipe off any excess metal residue left behind by the process. Depending on taste level, finish off with some oiling if necessary to protect your newly sharpened tool from further rusting or corrosion over time; however, avoid oils like WD-40 as these will damage most common kitchen knives’ surfaces and make them less safe to use!

Why Use a Knife Sharpener?

A diamond knife sharpener is a great tool to have in your kitchen as it can easily and quickly sharpen dull or damaged blades, making them once again efficient. Not only is this convenient but it also improves the safety of your knives as dull knives are more likely to cause you harm. Additionally, using a diamond knife sharpener will ensure that your knives last longer, saving you money in the long run.

Using a diamond knife sharpener takes a few simple steps:

1. First, decide whether you need to sharpen the entire blade or just focus on its tip. This will depend on how blunt or damage the knife is.

2. Position the blade at an angle of between 10-20 degrees against the sharpening stone that comes with your diamond knife sharpener. The stone should face away from you for safety reasons.

3. Start moving the blade across the stone in one direction—back and forth or side to side—ensuring that even pressure is applied at all times. Wait 3-5 seconds before changing direction while still maintaining consistent movement across the stone surface.

4. At frequent intervals throughout this process, hold up the blade to check its level of sharpness and adjust pressure where necessary either during or between passes until you have achieved satisfactory results.

5. Finally, rinse off any filed metal particles from around your knife before using it for meal preparation purposes to keep your food clean and safe to eat!

Understanding Different Angle Degree Options

A diamond knife sharpener is an invaluable tool for keeping kitchen knives razor sharp. Different angle degree options are available, making it a versatile tool that can be used to sharpen a variety of knife styles. The primary angle degrees offered range from 10 degrees to 20 degrees. Generally speaking, higher-end kitchen knives should be sharpened at a lower angle degree and less expensive table knives should use a higher angle degree. Varying the angle degree can also work well when trying to adjust the type of cutting edge produced by the sharpener – it will vary in its sharpness and thickness depending upon the angle degree used. Many sharpeners also offer interim gradient steps between the basic levels so that the user has more control to get their preferred result. When shopping for a diamond knife sharpener, look for those that come with angle guides or adjustable settings so you have more control over the angle degree being used and will produce better results when sharpening different types of knives.

Selecting the Right Sharpening Stone

When choosing a diamond knife sharpener, it’s important to select the right stone for the job. While natural stones can be costly and messy to use, synthetic diamond stones are perfect for knife sharpening and come in a variety of grits. A lower grit stone (typically marked 500 to 1000 Grit) is ideal for repairing damaged edges, such as chips or nicks, while #1000 – #3000 grit stones are best for general purpose sharpening. Once you’ve got your diamond stone, adjusting the angle of the blade so that it is angled correctly against the surface of the stone is also important. A blade should have an angle between 10 and 20 degrees which will ensure that you get an even edge on your knife.

Once preparing your sharpener is complete, it’s time to use it! Before beginning, moisten either side of your sharpening surface with water or light oil. Moistening will helps ensure a consistent edge whilstsharpening. Then press the blade against the sharpener in an arching motion, applying moderate pressure while keeping an eye on the shape and angle of blade’s edge as you sharpen each side by rubbing from hilt to tip multiple times. Be sure to test if it’s been sufficiently sharpened by slicing through a few sheets of paper or cutting through some vegetables – you should feel almost no resistance when cutting through them both! If there is any resistance then repeat this process until a satisfactory result is achieved. Finally, clean off any residue from your knife before stowing away for future use.

Learn the Sharpening Technique

Before you start, it is important to understand the technique required when sharpening knives with a diamond knife sharpener. You will run the blade along the diamond-coated rod at the same angle that your original grind was set at – usually between 15 and 20 degrees. Then, using light pressure, move the blade in an “S” pattern, alternating between right and left sides of the blade as you draw it forward. Do this a few times on each side while rotating and releasing pressure every so often (a few strokes at a time). Again, be sure to use light pressure. Do not saw back and forth over the sharpener; too much pressure can cause damage.

Next, use medium to fine grit honing steel available to further sharpen your knife—this should also be done using an angled stroke pattern across the steel at no more than 15 to 20 degrees. Follow up with a few strokes on both sides of the blade, again alternating between left and right. Once finished, clean off any particles from your knife with a cloth before use or storage. Finally, always store knives properly to avoid dulling them quickly and causing unnecessary damage such as chips in the blade edge.

Sharpening Your Knife

1. Start by gathering the necessary items for sharpening your knife: a diamond knife sharpener and a damp cloth.

2. Place the knife blade on the sharpener so that the blade is touching one of the diamond-covered surfaces. You want to make sure that both edges of the blade stay in contact with the surface of the sharpener for an even result when you are finished.

3. Gently pull the blade through the sharpener in a sweeping motion, ensuring that it is always in contact with both sides of the diamond-covered surface, as well as being pulled down against its cutting edge while dragging it through.

4. Repeat steps 2 and 3 on alternating sides until you have evenly sharpened both edges to your desired level of clarity. Be careful not to over sharpen; holding each side too long can cause damage or too much wear on your blade’s edge.

5. Once finished, wipe off any debris from your knife with a damp cloth and enjoy your now ultra-sharp knives!

Maintaining the Sharpener

A diamond knife sharpener is an invaluable tool for keeping your knives in top shape and ensuring that they stay sharp. However, like all tools, it requires proper care and maintenance to ensure optimal performance. Here are some tips for cleaning and storing your diamond knife sharpener.

1. Clean the Body: To keep the body of the sharpener free from rust and dirt buildup, use warm water, soap, and a soft cloth or sponge to wipe down the surface once a month. Avoid using steel wool or stiff brushes as this could damage the surface.

2. Clean the Core: Once a year, use a soft-bristled brush to clean out any dirt buildup inside the core of your knife sharpener. This step ensures there is no debris clogging up any slots or blades on the sharpening surface of the tool which can reduce its effectiveness over time.

3. Oiling: For durability and protection against rust, regularly apply food-grade oil to all metal components of your diamond sharpener such as hinges, screws, and compartments where lubrication is needed. This can help extend its life and ensure it keeps working at its best over time!

4. Storage Conditions: Your diamond knife sharpener should be stored in a dry place away from extreme temperatures, moisture or humidity which can cause corrosion or damage to its components over time if not properly cared for. Store it in its original packaging if possible as this will provide extra protection from any outside elements that may affect its performance in the long run!

Troubleshooting Tips

Using a diamond knife sharpener can be a fast and efficient way to keep your knives sharp. Here are some troubleshooting tips for using this type of sharpener:

1. Angle – When sharpening with a diamond knife sharpener, it is important to angle the blade properly in relation to the sharpening stone. Generally, an angle of 10-15 degrees is ideal. If you don’t angle the blade correctly, it can actually dull the edge instead of sharpen it.

2. Pressure – Make sure to only apply moderate pressure when running the blade over the sharpening stone. If too much pressure is used, it can actually damage or chip away at the blade’s edge while not doing any good in terms of making the blade sharper.

3. K eep i t p lu nged – Keeping a coolant such as water or oil on the diamond knife sharpener during use helps keep friction at bay and will also help remove shavings and particles accumulated on its surface due to wear and tear from frequent use.

4. Rotation – Move the blade from heel to tip along the stone in one fluid motion and switch sides periodically for even wear and tear of both edges . This keeps both sides of the blade evenly chamfered for better overall sharpness and performance .


Using a diamond knife sharpener is an easy and effective way to ensure a razor-sharp knife edge every time. Start by clamping the sharpener on a flat surface. Place the angle of the blade against the guide in the sharpener, then pull it forward and back about 10 to 20 times. Wipe your blade clean and check for any burrs or uneven edges. If necessary, repeat with more passes and check the blade often. With regular use, this will help maintain that “like new” feeling every time you reach for your knife.
