Understanding  how to use Diamond Sharpening Stones:

What are Diamond Sharpening Stones?

Diamond sharpening stones, also known as diamond whetstones or diamond plates, are abrasive surfaces with industrial-grade diamonds bonded to the base. Unlike traditional oil or water stones, diamond sharpeners use a harder material that can sharpen extremely hard steel and other metals effectively. The diamond particles provide a fast cutting action, making the sharpening process quicker and more efficient.

How Do They Work?

When you run the edge of a blade or tool across the diamond surface, the diamonds abrade the metal, creating a new sharp edge. The abrasive nature of diamonds allows them to maintain their cutting ability for a long time, ensuring longevity and consistency in the sharpening process.

Advantages of Diamond Sharpening Stones:

Fast Sharpening: Diamond stones are incredibly efficient and can remove material quickly, saving you time and effort.

Versatility: They can be used to sharpen a wide range of tools, including knives, scissors, chisels, and even garden tools.

Durability: Diamond stones have a long lifespan and do not require flattening or maintenance like traditional sharpening stones.

No Soaking Needed: Unlike water stones, diamond sharpeners do not need soaking, making them convenient and ready to use at any time.

Choosing the Right Diamond Sharpening Stone:

Grit Sizes and Their Uses:

Diamond sharpening stones come in various grit sizes, and each serves a specific purpose. Coarse grits, such as 200 to 400, are used for repairing damaged or dull edges. Medium grits, ranging from 600 to 1000, are ideal for regular maintenance and sharpening moderately blunt blades. Fine grits, starting from 1200, are used for honing and refining edges to razor sharpness.

Consideration for Knife Types:

Different knives require different sharpening techniques. For instance, a kitchen knife may need a polished and razor-sharp edge, while a hunting knife may benefit from a slightly rougher edge for increased durability. Consider the intended use of your knife before selecting the appropriate grit size.

Size and Durability:

The size of the diamond sharpening stone matters when it comes to sharpening larger tools or knives. A larger stone offers more surface area and allows for longer strokes, making it easier to maintain a consistent edge. Additionally, opt for a high-quality diamond stone to ensure it withstands heavy use over time.

Step-by-Step Guide to Using a Diamond Sharpening Stone:

Preparing the Stone:

Before using your diamond sharpening stone, it’s essential to ensure it is clean and free from any debris or contaminants. Use water and a soft brush to clean the surface thoroughly. If you have a double-sided stone with different grits, choose the appropriate side for your initial sharpening process.

How to Use Diamond Sharpening Stone

Proper Angle and Technique:

To get the best results, the proper sharpening angle must be maintained. Most kitchen knives require a sharpening angle between 15 and 20 degrees. Hold the knife firmly and steadily against the stone, making sure the blade edge contacts the diamond surface consistently.

Progression of Grits:

For the best results, use a progression of grits, starting from coarse to fine. Begin with a coarse grit to repair the blade, and then move to medium and fine grits to refine the edge. Each progression removes the scratches left by the previous grit, resulting in a smoother and sharper edge.

Cleaning and Maintenance:

After sharpening, clean the stone using water and a soft brush to remove any metal shavings or residue. Properly store the diamond sharpening stone in a dry and safe place to prevent any damage or contamination.

Sharpening Different Tools with Diamond Sharpening Stones:


Diamond sharpening stones are highly effective for sharpening kitchen knives, pocket knives, and hunting knives. The diamond surface quickly restores the sharpness of the blade, allowing for precise cuts and reduced effort during use.

Scissors and Shears:

Scissors and shears can become dull with time, making cutting tasks frustrating. Diamond sharpening stones offer a solution to restore the cutting edges of scissors, allowing for smoother and cleaner cuts.

Chisels and Woodworking Tools:

Woodworking chisels and tools often require precise sharpening to maintain their performance. Diamond sharpening stones excel in providing a finely-honed edge for chisels, ensuring clean and accurate cuts in woodworking projects.

Tips and Tricks for Effective Sharpening:

Common Mistakes to Avoid:

Applying too much pressure on the blade while sharpening, which can lead to uneven edges.

Overlooking proper angle maintenance results in a less effective sharpening process.

Neglecting to clean and maintain the diamond sharpening stone, reduces its lifespan and effectiveness.
