A diamond sharpening stone is an excellent tool used to sharpen and maintain a sharp edge on your knives, blades, and tools. These stones are very hard and durable, as they are made out of industrial diamonds that have been engineered specifically for the purpose of sharpening. While traditional natural stone sharpeners wear down over time with repeated use, diamond sharpening stones last longer than other types of stones and require minimal maintenance to keep it in top condition.

Using a diamond sharpening stone is relatively straightforward and simple. The process involves using both coarse and fine grit diamond abrasives to successively ‘sharpen’ the knife edge to an appropriate level. Coarse grit abrasive is used at the beginning because it quickly removes large amounts of material from the blade which can then be further refined with finer grits until the desired level of keenness is reached. First wet your diamond stone before you begin honing, this will help the abrasive particles ‘float’ across the surface of the stone more easily while keeping its cutting power constant. Then you should run the blade across both sides of the stone at a slightly diagonal angle with light downward pressure for about 20-30 strokes each side or until you achieve a nice even burr along both edges of your blade. Finally move up to successively finer grades in order to achieve an incredibly keen razorsharp edge. To finish up, lightly stropping your edge against leather or microfiber cloth can further refine it into something beautiful!

Before You Begin

Gather Your Supplies

Before you begin sharpening your knife with a diamond sharpening stone, you’ll need to gather the necessary supplies: your diamond sharpening stone, a clean cloth or paper towel, and sandpaper.

Understand Safety Protocols

Sharpening stones can quite easily slip due to their smooth surfaces. It’s important to understand the safety protocols that come along with using a sharpening stone. Make sure you are wearing protective eyewear and gloves while grinding. And take extra precautions by using a cutting board or other protective surface beneath your diamond sharpening stone as it may cause surface scratches when slipped. Additionally, be sure to keep fingers and hands away from the blade of the knife when pressing against the stone for best results.

Prepare Your Work Area
Make sure there is ample workspace when preparing to sharpen your knife; having enough pressure is key in getting the optimal grind from your diamond sharpening stone. Make sure there are no cables or cords nearby that could become hindering factors – any disruptions could cause unsafe conditions while grinding quickly. Lay out all of your equipment ahead of time so that it is easy to reach and convenient for you once you start the process.

Cleaning Your Blade and Identifying The Steel Type

Before you begin to use a diamond sharpening stone, it is important to clean your blade and identify the steel type. Accurately identifying the type of steel will help ensure that you use the correct grit for the job. Safety considerations such as wearing protective eyewear when working with blades should also be taken into account at this stage. After inspecting your blade, check for any superficial damage or excessive wear of the edge would reveal whether it is suitable for sharpening on a diamond stone or other sharpeners.To ensure hygiene and avoid cross-contamination when sharpening different blades or knives, sanitize the blade prior to sharpening either by using an appropriate cleaner or wiping off with a cloth soaked in alcohol. Once all of these steps have been taken, you are ready to begin sharpening your blade with a diamond sharpening stone!

Optimal Grits and Profiles

Once you’ve selected an appropriate sharpening stone for your blade, it’s important to choose the right grit. Different blades have different profiles and will require different levels of coarseness in order to find the desired edge. Generally speaking, diamond sharpening stones range from 300-3000 grits, with 500-800 being the most common preference. The lower the number, the coarser or more aggressive it is. Medium/fine stones are suitable for general purpose knife maintenance and repair while finer/superfine stones are ideal for very fine work such as touch-ups and finishing on extremely hard steel.

A blade with a beveled or convex edge requires a much higher grit than one that has a flat cutting edge. For a beveled edge, use something in the range of 2000 to 3000 grit while flat blades generally need only 500gritto 1000 grit to produce the desired level of sharpness. It can also help to look up information about your particular blade’s profile in order to determine what type of sharpening stone is best suited for it. If all else fails, opt for a medium/fine stone, as this will usually work for any typical application.

Sharpening Techniques

Sharpening Techniques

Diamond sharpening stones are effective and easy to use, allowing you to quickly sharpen knives and other tools. To use them correctly, it’s important to understand the right techniques and implement them correctly. Depending on the blade profile and preferred finish, different honing techniques need to be used for best results.

For instance, a “V-shape” blade profile requires a somewhat greater angle between the stone and knife as compared to a straight edge knife. This is done by pushing the knife forward when sharpening and by gently raising it from one side of the diamond stone to the other. Using this technique, a level grind should be achieved across both edges of the blade simultaneously.

Angle Considerations

Holding your knife edge on an incorrect angle can ruin its performance or ruin your desired finish on the blade edge. For consistent results it is important that you keep your diamond sharpening stone at an consistent angle with respect to each pass over the cutting edge. Start with a low angle and adjust accordingly based on how often you plan or need to sharpen your specific tool or application. This could vary from 15 degrees per side up to 30 degrees per side depending on preference and usage patterns; with kitchen cutlery tending towards lower angles (15-20) while tools typically requiring increased strength such as machetes, hatchets and cleavers would opt for higher angles (25-30).

Recommending Oil For A Consistent Finish

Diamond stones tend not to require much lubrication in order for them work effectively, however some recommend using oil such as mineral oil or vegetable oil as it does help provide some protection against wear of both your diamond sharpening stone and your knife during prolonged use. If using honing oil ensure you rinse off any excess lubricant after each use as high residual oils can breakdown abrasive surfaces causing premature dulling of diamond stones due their break down into smaller abrasive particles .

Storage Solutions

Storage Solutions: When not in use, it is important to store diamond sharpening stones properly in order to ensure a long lifetime of service. A stone can be folded and encased for storage- this is possible with some flat diamond stones or whetstones. If folding is not an option, the stone can be rolled up into a cylinder and safely stored container like a tube or cylindrical container. It is also recommended to always store your sharpening stones in a dry and ventilated area as excess humidity can degrade their quality over time.

Optimal Storage Container Options: The best option for storing of diamond sharpening stones are PVC tubes, plastic containers and aluminum grinders specially designed for most flat diamond sharpening stones and whetstones. This offers a protective case that allows consumers easy portability while also protecting their sharpeners when transferring abroad etc.

Cleaning & Maintaining The Stone After Use: After using your Diamond Sharpening Stone, make sure to wash it off with lukewarm water and then leave it out to air dry. It should never be manually dried off using any type of cloths as this will immediately damage the surface of the stone. Once fully dry you may use an abrasive pad such as 240 grit sandpaper to resurface the stone for full rejuvenation of its oily protective layer after repeated usage wear off’s over time. This will help you keep your stone performance at its peak condition alongside with appropriate storage techniques!


Diamond sharpening stones are an incredibly effective and efficient way of keeping your blades and tools sharp. They offer superior edge performance, and most importantly, can provide a long lasting, razor-sharp finish. In addition to this benefit, diamond stones are suitable for any knife steel that you may have, including Japanese steels. To get the most out of your diamond stone, make sure you keep it clean after every use. Establish a maintenance routine with regular washes so that your stone remains free from all abrasive material or build-up due to continual use. This will help ensure your diamond stone will continue delivering optimal performance for many years to come!
