When it comes to woodworking, having sharp chisels is essential. But what grit should you use to sharpen your chisels? The answer depends on the condition of your chisels and what you want to achieve with them. 
Coarse grits, such as 120 or 220, are great for removing nicks and reshaping the edge of the chisel. Medium grits, like 400 or 600, are ideal for honing and refining the edge. Finally, finer grits, such as 1000 or 2000, are necessary for creating a razor-sharp edge. Understanding grits and their uses is crucial to achieving optimal results when sharpening your chisels. To start, it’s important to examine the condition of your chisels. If your chisels have a relatively sharp edge, you can start with a finer grit between 1000-2000 to maintain the sharpness. However, if your chisels are dull or have nicks, you’ll need to start with a coarser grit to reshape the edge before moving on to finer grits. By choosing the right grit for the specific task at hand, you can achieve the best results when sharpening your chisels.
Understanding Grit Sizes
https://www.youtube.com/watch?v=ZGg0P5UTNho&embed=true When it comes to sharpening chisels, understanding grit sizes is essential. Grit refers to the number of abrasive particles per square inch on a sharpening stone. The higher the number, the finer the grit. Here are the three main grit sizes used for sharpening chisels:
Coarse Grit
Coarse grit stones have a grit size of 100-400. They are ideal for reshaping or repairing damaged chisels, as they remove a lot of material quickly. However, they leave a rough finish and can create scratches on the blade. Coarse grit stones are not recommended for regular sharpening.
Medium Grit
Medium grit stones have a grit size of 800-1000. They are the most commonly used grit size for sharpening chisels. They are ideal for removing nicks, chips, and burrs while creating a sharp edge. Medium grit stones are versatile and can be used for both regular maintenance and repair work.
Fine Grit
Fine grit stones have a grit size of 2000-8000. They are used for honing and polishing the edge of a chisel, creating a razor-sharp finish. Fine grit stones are not recommended for repairing damaged chisels, as they remove very little material. They are best used for maintaining a sharp edge on a well-maintained chisel. In conclusion, understanding grit sizes is crucial for sharpening chisels. Using the right grit size for the task at hand will ensure that your chisels are sharp and ready to use.
Choosing the Right Grit for Chisels
https://www.youtube.com/watch?v=mykEwTerU08&embed=true As I mentioned earlier, having the right grit sharpening stone for chisels is crucial. But what grit should you use? Here’s a guide to help you choose the right grit for your chisels.
Starting Grit
If your chisels are very dull or damaged, you’ll want to start with a coarse grit stone. A coarse grit stone will remove more material from the chisel, so it’s important to use it carefully. Starting with a coarse grit stone will help you get your chisels back into shape quickly.
Progressive Grits
After you’ve used a coarse grit stone to get your chisels back into shape, you’ll want to move on to a medium grit stone. The medium grit stone will refine the edge of your chisels and remove any scratches left by the coarse grit stone. Once you’ve used the medium grit stone, you’ll want to move on to a fine grit stone. The fine grit stone will polish the edge of your chisels and make them razor sharp.
Finishing Grit
If you want an even sharper edge on your chisels, you can use an extra-fine grit stone after the fine grit stone. The extra-fine grit stone will give your chisels an even smoother and more polished edge. Here’s a table to summarize the grits you should use for sharpening your chisels:
| Grit | Use |
|---|---|
| Coarse | For very dull or damaged chisels |
| Medium | To refine the edge and remove scratches |
| Fine | To polish the edge and make it razor sharp |
| Extra-fine | For an even sharper and more polished edge |
Remember, it’s important to use the right grit sharpening stone for chisels to ensure that they are sharp and effective in creating clean cuts.

Applying the Grit
When sharpening chisels, it is important to use the right grit for the job. Coarser grits, such as 120 or 220, are ideal for removing nicks and reshaping the edge of the chisel. Medium grits, such as 400 or 600, are great for honing and refining the edge, while finer grits, like 1000 or 2000, are necessary for creating a razor-sharp edge. Always start with the coarsest grit and work your way up to the finest grit. To apply the grit, wet the sharpening stone with water or oil, depending on the type of stone you are using. Then, place the chisel on the stone, making sure to keep the bevel flat against the stone. Move the chisel back and forth, applying even pressure, until you have sharpened the entire bevel.
Sharpening Motion
When sharpening chisels, it is important to use the right sharpening motion. The most common motion is the push stroke. To use this motion, place the chisel on the stone, bevel flat against the stone, and push the chisel forward while maintaining even pressure. Lift the chisel off the stone after each stroke and repeat until the entire bevel has been sharpened. Another sharpening motion is the circular motion. To use this motion, place the chisel on the stone, bevel flat against the stone, and move the chisel in a circular motion while maintaining even pressure. Lift the chisel off the stone after each stroke and repeat until the entire bevel has been sharpened.
Maintaining the Edge
After sharpening your chisel, it is important to maintain the edge. To do this, use a honing guide to hold the chisel at the correct angle and hone the edge with a fine-grit sharpening stone. Make sure to use light pressure and keep the bevel flat against the stone. To keep your chisel sharp, it is important to hone the edge regularly, especially if you use the chisel frequently. A sharp chisel not only makes your work easier, but it also produces cleaner cuts and reduces the risk of injury.
Maintaining Your Chisels
Post-Sharpening Care
After sharpening your chisels, it is important to take proper care to ensure that they remain sharp and in good condition. Here are some post-sharpening care tips:
- Clean the chisels thoroughly with a cloth to remove any debris or metal shavings.
- Apply a thin coat of oil or wax to protect the metal from rust and corrosion.
- Store the chisels in a dry place to avoid moisture buildup.
Regular Maintenance
Regular maintenance is essential to keep your chisels in good working condition. Here are some tips for maintaining your chisels:
- Inspect the chisels regularly for any signs of damage or wear.
- Sharpen the chisels as needed to maintain a sharp edge.
- Keep the chisels clean and free of debris to prevent damage to the blade.
Long-Term Storage
If you plan to store your chisels for an extended period of time, it is important to take the proper steps to ensure that they remain in good condition. Here are some tips for long-term storage:
- Clean the chisels thoroughly and apply a coat of oil or wax to protect the metal from rust and corrosion.
- Store the chisels in a dry place with low humidity to prevent moisture buildup.
- Wrap the chisels in a soft cloth or protective cover to prevent damage to the blade.
By following these tips for post-sharpening care, regular maintenance, and long-term storage, you can ensure that your chisels remain sharp and in good working condition for years to come.
