Sharpening chisels with a sharpening stone is a crucial skill every carpenter and woodworker should master. As chisels are essential tools for any woodworking project, it is important to keep them sharp for precise and efficient cutting. Using a sharpening stone and guide can help you achieve razor-sharp chisels, ensuring clean and accurate cuts in your woodworking projects.
Firstly, choose the right sharpening stone for your chisels. Sharpening stones come in various grits, ranging from coarse to fine. Coarser stones are used for repairing damaged blades or reshaping bevels, while finer stones are ideal for honing and polishing the edges. It’s recommended to start with a medium-grit stone and work your way up to finer ones.
Before you start sharpening, make sure your chisel is clean and free from any debris or dirt. This will prevent scratching the sharpening stone and ensure better results. Secure the chisel in a sharpening guide to maintain a consistent angle while sharpening. The angle will vary depending on the bevel angle of your chisel, so refer to the manufacturer’s guidelines or use a protractor to determine the correct angle.
Now you’re ready to start sharpening. Apply a few drops of honing oil or water to the sharpening stone to lubricate the surface. Holding the chisel securely in the sharpening guide, position it on the stone at the desired angle. Move the chisel back and forth along the stone, covering the entire bevel. Apply light pressure and ensure consistent strokes. Remember to maintain the angle and alternate sides regularly to achieve an even edge.
Continue sharpening until you achieve a burr on the edge of the chisel. You can feel the burr by lightly running your finger along the backside of the chisel. Once you have a burr, switch to a finer-grit stone and repeat the sharpening process. This will remove any scratches or roughness left by the coarser stone and refine the edge of your chisel.
After sharpening on the finer-grit stone, remove the burr by lightly stroking the chisel along the stone a few times without applying pressure. This will help achieve a sharp and smooth edge. Finish the sharpening process by carefully honing the chisel’s backside on the sharpening stone to remove any burrs or rough edges.
Finally, test the sharpness of your chisel on a piece of wood or scrap material. If the chisel effortlessly cuts through the material with clean and precise cuts, you have successfully sharpened your chisel. If not, repeat the sharpening process with finer-grit stones until you achieve the desired sharpness.
Regularly sharpening your chisels with a sharpening stone and guide will not only enhance the performance and longevity of your chisels but also improve the quality of your woodworking projects. With practice and patience, you’ll be able to achieve razor-sharp chisels that will make your woodworking tasks more enjoyable and efficient.

Using a sharpening guide is highly recommended for beginners and professionals alike. It simplifies the sharpening process and enhances the overall effectiveness of chisel sharpening.
Angle the Chisel Properly
When sharpening your chisel, one of the most important factors to consider is the angle at which you hold the chisel against the sharpening stone. The angle you choose will determine the sharpness and durability of the cutting edge.
For most chisels, a sharpening angle of around 25 to 30 degrees is recommended. This angle provides a good balance between sharpness and durability. However, it’s important to note that the optimal angle can vary depending on the type of chisel and the specific task you’re using it for.
To achieve the proper angle, start by placing the chisel on the sharpening stone with the bevel flat against the stone and the cutting edge facing downward. Then, tilt the chisel slightly until you reach the desired angle. It’s important to maintain a consistent angle throughout the sharpening process to ensure even sharpening of the cutting edge.
A common technique for maintaining a consistent angle is to use a sharpening guide. This handy tool attaches to the chisel and helps you maintain the desired angle as you move the chisel along the sharpening stone. Sharpening guides are especially useful for beginners who may have difficulty holding the chisel at the correct angle by hand.
As you sharpen the chisel, make sure to apply even pressure and slide the chisel back and forth along the length of the sharpening stone. This will help remove any burrs or imperfections on the cutting edge, resulting in a sharp and smooth chisel.

Begin Sharpening with Coarse Grit
Before you begin sharpening your chisels, it’s important to understand the different grits of sharpening stones. Grit refers to the coarseness of the stone, and it can range from coarse to fine. The coarse grit stones usually have a lower number, such as 100 or 200, while the fine grit stones have higher numbers, such as 1000 or 2000.
When starting with sharpening your chisels, it’s best to begin with a coarse grit stone. This will help remove any dull or damaged edges on the chisels quickly and efficiently.
Step 1: Prepare the Stone
Before using the coarse grit stone, make sure it is clean and free of any debris. You can do this by using a brush or cloth to wipe away any dirt or particles.
Step 2: Apply Honing Oil
Next, apply honing oil to the surface of the sharpening stone. Honing oil helps lubricate the stone and allows for smoother sharpening.
Note: If you don’t have honing oil, you can also use water as a lubricant. However, keep in mind that water can cause the stone to wear down faster.
Step 3: Hold the Chisel Properly
To begin sharpening, hold the chisel firmly with one hand. Make sure to hold it at a consistent angle, typically around 20 degrees, although this may vary depending on the type of chisel and your personal preference.
Tip: It’s a good practice to mark the desired angle on the chisel with a pencil or marker to ensure consistency throughout the sharpening process.
Step 4: Start Sharpening
Place the beveled edge of the chisel against the coarse grit stone. Using moderate pressure, move the chisel back and forth in a sweeping motion. Make sure to maintain a consistent angle as you sharpen.
Tip: To prevent uneven wear on the stone, it’s important to distribute your strokes evenly across the surface. This can be achieved by using a circular or figure-eight motion.
Continue sharpening until you feel a burr on the opposite side of the chisel. A burr is a small, raised edge that indicates the chisel is sharp.
Note: It’s crucial to check the progress regularly to ensure you don’t oversharpen or damage the chisel.
Once you’ve achieved a burr, you can move on to a finer grit stone for further sharpening and honing. Remember to clean the coarse grit stone properly before storing it.
Finish Sharpening with Fine Grit
A fine grit sharpening stone is typically between 600 and 2000 grit. This finer grit will help refine the edge of your chisel and remove any remaining burrs or imperfections left by the coarser stone.
To start, wet your fine grit sharpening stone and place it on a stable surface. Hold your chisel at a 20-degree angle and gently press the cutting edge onto the stone. Use light, consistent pressure and perform a few passes on each side of the chisel.
Keep in mind that the goal is to maintain the 20-degree bevel angle you established during the initial sharpening. Pay close attention to ensure consistency in your strokes.
As you work, periodically feel the edge of the chisel with your fingertips. You should feel a slight burr along the cutting edge. This burr is an indicator that you are removing material and refining the edge.
When you no longer feel a burr, it means you have achieved the desired sharpness. At this point, you can finish sharpening by honing the chisel on a strop or leather strip, or move on to the next step in your woodworking project.
Remember to clean your sharpening stones thoroughly after each use, as metal particles can build up and affect their performance. Store them in a dry place to prevent any rusting or damage.
By following these steps, you can ensure that your chisels are properly sharpened and ready to tackle any woodworking task with precision and efficiency.
