Best Sharpening Stones

Whetstones have a long history dating back thousands of years, originating from various cultures around the world. These sharpening tools were essential for honing the edges of blades, knives, swords, and other cutting implements.

1. Early Origins: The use of whetstones can be traced back to ancient civilizations such as the Egyptians, Greeks, and Romans. These early whetstones were typically made from various natural materials like slate, sandstone, or novaculite (a type of fine-grained sedimentary rock).
2. Roman Era: Romans used natural stones like Novaculite (found in regions like Arkansas in the USA) as whetstones. They recognized the importance of maintaining sharp edges on their swords and knives.
3. Medieval Europe: During the Middle Ages, whetstones continued to be crucial tools for sharpening blades. They were often used by blacksmiths, knights, and craftsmen to maintain their weapons and tools.
4. Industrial Revolution: With the advent of industrialization, the production of whetstones evolved. Natural stones were still used, but synthetic alternatives like carborundum (a silicon carbide) became more prevalent due to their consistent quality and availability.
5. Modern Era: In recent times, synthetic whetstones made from materials like aluminum oxide or silicon carbide are commonly used. These synthetic stones offer consistent particle distribution, allowing for more precise sharpening.
6. Varieties of Whetstones: Whetstones come in various shapes, sizes, and grits. The grit determines the coarseness or fineness of the stone and affects the sharpness of the edge. Coarser grits remove more material and are used for repairing damaged edges, while finer grits are for honing and polishing.
7. Water Stones and Oil Stones: Whetstones can be categorized as water stones or oil stones based on the lubricant used during sharpening. Water stones require soaking in water before use, while oil stones use oil as a lubricant to float away metal shavings.
8. Diamond and Ceramic Whetstones: Besides traditional materials, diamond and ceramic whetstones have gained popularity due to their hardness and durability. Diamond stones, coated with industrial diamonds, are exceptionally hard and durable, while ceramic stones offer consistent sharpening properties.

Throughout history, whetstones have been essential tools for craftsmen, chefs, hunters, and anyone needing sharp blades. Their evolution from natural to synthetic materials has greatly improved the consistency and effectiveness of blade sharpening techniques

Disadvantages of Sharpening Stones

• Time-consuming
  Sharpening with stones can be a time-consuming process, especially for beginners. Achieving the desired level of sharpness requires patience, practice, and skill.
• Skill-dependent
  Properly sharpening a blade with a stone requires skill and technique. Novices might find it challenging to maintain a consistent angle while sharpening, which can result in uneven sharpening or even damage to the blade.
• Potential for damage
  Incorrect use of sharpening stones can damage the blade. Applying too much pressure or using the wrong angle can lead to nicks, scratches, or even the creation of an uneven edge.
• Multiple grits required
  To achieve a razor-sharp edge, multiple grits of sharpening stones may be necessary. Coarser stones are used for initial sharpening, while finer grits are used for refining the edge. Owning and managing multiple stones can be cumbersome and expensive.
• Maintenance
  Sharpening stones themselves require maintenance. They can become uneven or clogged with metal particles, diminishing their effectiveness over time. Regular cleaning and flattening of the stone’s surface are necessary for consistent sharpening results.
• Portability
  Carrying sharpening stones for outdoor or on-the-go purposes can be inconvenient due to their weight and the need for multiple grits. This limitation can be addressed by smaller, portable options, but they might not offer the same precision or versatility as larger stones.
• Limited use for certain blades
  Not all blades are suitable for sharpening with stones. Serrated blades or blades with extremely hard steel may require specialized equipment or professional sharpening services.

Benefits of Sharpening Stones

1. Versatility
   Sharpening stones are versatile and can be used for various types of blades and cutting tools. They are suitable for kitchen knives, hunting knives, woodworking tools, and more.
2. Control over Sharpness
   They provide users with control over the sharpness level. Different grits of stones allow us to achieve varying levels of sharpness, from coarse for repairing damaged edges to fine for polishing and refining the edge to razor sharpness.
3. Long-term Cost Savings
   Investing in sharpening stones can save money in the long run compared to frequent professional sharpening services or purchasing new knives. They extend the lifespan of our blades by regularly maintaining their edges.
4. Skill Development
   Using sharpening stones improves our sharpening skills over time. While it might require practice, learning how to use a sharpening stone effectively can lead to better results and increased confidence in maintaining our tools.
5. Customization of Edge Angles
   Sharpening stones allow customization of the angle at which the blade is sharpened. Different tools might benefit from different angles, and stones provide the flexibility to adapt to these needs.
6. Controlled Material Removal
   They offer control over the amount of material removed during sharpening, which is particularly advantageous when dealing with expensive or specialized blades where precision is crucial.
7. No Power Requirement
   Unlike some electric sharpeners, sharpening stones do not require electricity, making them an ideal choice in situations where power sources might be limited or unavailable.
8. Reliable Edge Maintenance
   When properly used and maintained, sharpening stones consistently deliver reliable results, ensuring our tools remain sharp and efficient.
9. Enhanced Safety
   A sharp blade is safer to use than a dull one. Sharpening stones help maintain the blade’s effectiveness, reducing the likelihood of slips or accidents caused by a dull edge.

How to use Sharpening stones

1. Prepare the Stone
   If we’re using an oil stone, apply a few drops of honing oil on the coarse side of the stone. For a water stone, soak it in water for the recommended time according to the manufacturer’s instructions.
2. Determine the Angle
   Most knives are sharpened between 15 to 30 degrees. If we’re unsure about the angle, try to match the existing angle of the blade.
3. Hold the Blade
   Hold the knife firmly with the blade facing away. Use the dominant hand to grip the handle and the other hand to steady the blade on the stone.
4. Start with the Coarser Grit
   Place the blade’s edge against the coarse side of the stone at the determined angle. Start with the tip of the blade and move towards the base, applying light pressure.
5. Maintain Consistent Angles
   Keep the blade at a consistent angle as we move it across the stone. Use smooth, even strokes, ensuring that the entire edge comes into contact with the stone.
6. Alternate Sides
   After several strokes, alternate to the other side of the blade, maintaining the same number of strokes on each side to ensure even sharpening.
7. Check for Burr
   As we sharpen, we may feel a small burr or rough edge forming on the opposite side of the blade. This indicates that the first side is adequately sharpened.
8. Switch to Finer Grit
   Once satisfied with the sharpness on the coarse side, flip the stone to the finer grit side. Repeat the sharpening process using the same technique as before, starting from the tip and alternating sides.
9. Honing
   If available, finish the process by using a honing steel or leather strop to refine the edge and remove any remaining burr. Run the blade along the honing steel at a consistent angle, alternating sides.
10. Clean and Store
    Clean the sharpening stone with water (if it’s a water stone) or wipe off excess oil. Dry it thoroughly before storing it.

How to Maintain Sharpening Stones

1. Cleaning
   • After each use, clean the sharpening stone thoroughly to remove metal particles, debris, and residue.
   • For oil stones, use a cleaning solution or mineral spirits to remove the accumulated oil and debris. Scrub the surface gently with a brush.
   • Water stones can be cleaned with water and a brush to remove slurry and metal particles. Avoid using soap, as it can clog the stone’s pores.
2. Flattening
   • Over time, sharpening stones can become uneven due to wear or clogging. Flattening the stone helps maintain a level surface for consistent sharpening.
   • Use a stone fixer or flattening plate specifically designed for sharpening stones. Rub the fixer or plate against the stone’s surface in circular motions until it becomes flat.
3. Drying
   • Ensure the sharpening stone is completely dry before storing it to prevent mold or mildew growth.
   • Air-dry the stone thoroughly after cleaning, especially if it’s a water stone.
   • Some stones don’t like to be dried too quickly so avoid hot environments and direct sunlight.
4. Storage
   • Store the sharpening stone in a dry place away from moisture and direct sunlight.
   • Consider using a protective case or box to keep the stone clean and prevent it from getting damaged or chipped.
5. Avoid Contamination
   • Keep the stone away from contaminants like dirt, grease, or other substances that can affect its sharpening capabilities.
   • Avoid dropping or mishandling the stone to prevent cracks or chips.
6. Regular Maintenance
   • Periodically check the stone’s surface for wear, unevenness, or damage. Address any issues promptly to maintain its effectiveness.
   • Re-flatten the stone if uneven surface affecting sharpening results.
7. Proper Use
   • Follow manufacturer instructions regarding the use of the sharpening stone, including proper lubrication (if it’s an oil stone) and recommended cleaning methods.
   • Use the appropriate pressure and technique while sharpening to avoid unnecessary wear on the stone’s surface.

It’s not because other stones can’t be used as beginner stones, far from it. These stones are just cheap ones bundled up with some stuff we think we need when starting out.

As we progress on our knife journey and our skills are more honed, we realize that we don’t need all sort of things to achieve perfection. We just need one stone with a coarser grit and a finer one.

These stones aren’t really better than the others but better suited for personal preferences. At this level we most likely own a couple of knives that aren’t on the cheap side and hardly ever need to use lower grit stones to keep them lethally sharp.

We look at here are more durable sharpening stones and the quality of their grit distribution is far superior than the unreliable beginner ones. Which could mean that an #8000 grit beginner stone could feel rougher than a #3000 grit professional one.

Don’t look for whetstones with varying grit size on the opposing sides here. Most stones has it’s own grit and we have to buy them separately.
