WHETSTONES
Sharpen your blades
At The Cotswold Knife Company, we recognise the importance of maintaining your knives' sharpness for optimal performance and safety. That's why we offer a curated selection of premium whetstones from renowned brands such as Wüsthof, Lion Sabatier and KAI. Our collection is one of the best from all UK stockists which features grit levels to cover all sharpening tasks, ranging from 400 to 8000. Whether you are repairing a dull edge or honing a razor-sharp edge we are sure you will find a whetstone to suit.
These whetstones are the best in class, however, all whetstones can wear unevenly over time making it very hard to get a consistent sharp edge. So, to complement our whetstone selection, we also stock the Wüsthof Reshaping Stone which essentially allows you to reshape your whetstone and correct any unevenness caused by sharpening. By investing in quality sharpening tools and their adhering to proper maintenance, you enhance both the performance and lifespan of your knives.

FAQs
Whetstones come in a range of grit levels, each designed for a specific sharpening task. Choosing the right grit depends on the condition of your knife and how sharp you want the edge to be.
Coarse Grit (200 – 800) – For Repairing & Reshaping
- Removes chips, nicks, and restores damaged blades
- Quickly reshapes a very dull or blunt edge
- Best for repairing knives with significant wear
Medium Grit (800 – 2000) – For Regular Sharpening
- Ideal for general sharpening and edge maintenance
- Restores a working edge without being too abrasive
Fine Grit (3000 – 8000) – For Honing & Polishing
- Refines the edge to razor-sharp precision
- Ideal for Japanese knives or professional chef’s knives
- Higher grits (6000-8000) create a mirror-polished, ultra-sharp edge
Which Grit Should You Choose?
- If your knife is damaged or very dull ➝ Start with 400-800 grit
- If you need general sharpening ➝ Use 1000-2000 grit
- If you want a razor-sharp, polished edge ➝ Finish with 3000-8000 grit
Many professionals use a combination of grits, starting with a lower grit working their way to a medium stone (1000 grit), then refining with a fine stone (3000+ grit) for a razor-sharp finish.
When sharpening a knife on a whetstone, you should use a combination of both pushing and pulling motions. The correct technique involves sliding the blade forward (pushing) and then drawing it back (pulling) across the stone while maintaining a consistent angle.
Proper Whetstone Sharpening Technique:
- Maintain the sharpening angle specified by the manufacturer
- Use Even Pressure – Apply light but firm pressure as you push the blade forward, and then ease off slightly as you pull it back.
- Sharpen the Full Edge – Ensure the entire length of the blade makes contact with the stone during each pass.
- Work in Both Directions – Unlike some sharpening methods that only work in one direction, whetstone sharpening is effective in both pushing and pulling motions.
Common Mistakes to Avoid:
- Lifting the Blade Mid-Stroke – This can lead to an uneven edge. Keep consistent contact with the stone.
- Applying Too Much Pressure – Let the grit of the whetstone do the work—excessive force can damage the edge.
- Sharpening Only in One Direction – Using a smooth back-and-forth motion ensures even sharpening.
By pushing and pulling evenly, you create a razor-sharp, uniform edge, prolonging the lifespan of your knife and achieving optimal cutting performance.
It is always better to use a whetstone wet rather than dry. Whetstones are designed to work with water or oil to reduce friction and prevent overheating, which helps protect the knife blade and ensures a smoother sharpening process.
Why You Should Use a Wet Whetstone:
- Prevents Blade Damage – Lubrication reduces heat and friction, preventing excessive wear on the blade.
- Provides a Smoother Sharpening Process – Water or oil helps create a slurry, which enhances sharpening and removes metal filings effectively.
- Reduces Clogging – A dry whetstone can become clogged with metal particles, making it less effective over time.
- Increases Stone Longevity – Using water or oil helps the stone wear evenly, prolonging its lifespan.
