Oil stones are traditional sharpening tools that use oil as a lubricant during the sharpening process. They are available in different grits and can be either natural or synthetic. Oil stones are known for their longevity and ability to produce a sharp edge. However, they require regular maintenance, as the oil used can become contaminated with metal particles over time.


A sharpening jig is a useful tool that helps maintain a consistent angle while sharpening. It holds the blade securely and allows you to move it along the sharpening surface at a precise angle. Jigs come in various designs, including honing guides and blade clamps. Using a jig can greatly simplify the sharpening process, especially for beginners or those who struggle to maintain a consistent angle freehand.

Choose the sharpening system that best suits your needs and preferences. Experiment with different methods to find the one that produces the best results for you.

Now that you’ve chosen the right sharpening system, let’s move on to the sharpening process.

Sharpening Process

Setting the grinding/sharpening angle

The grinding or sharpening angle refers to the bevel angle that you’ll create on the blade. It determines the sharpness and durability of the cutting edge. Different tools may require different angles, so it’s essential to consult the manufacturer’s recommendations or consider the intended use of the tool. Some common angles for chisels range from 25 to 30 degrees, while plane blades often require a slightly higher angle of around 30 to 35 degrees.

Once you’ve determined the appropriate angle, you can proceed to the sharpening process.

Coarse sharpening

Start by securing your sharpening stone according to the manufacturer’s instructions. If using a water stone, soak it in water for the recommended amount of time before beginning.

Hold the chisel or plane blade firmly and position it on the stone with the bevel flat against the surface. Apply light pressure and move the tool back and forth across the stone, maintaining a consistent angle. Make sure to cover the entire bevel area evenly. Repeat this process several times, periodically checking the progress and adjusting your technique as needed.

Coarse sharpening removes any nicks, chips, or dullness from the blade, creating a new cutting edge.

Fine sharpening

After the coarse sharpening, it’s time to further refine and polish the blade. Switch to a finer-grit stone or move to the higher grit side of a dual-sided stone. Repeat the same sharpening motion as before, using lighter pressure. This step helps create a smooth and precise cutting edge.

Continue sharpening until you achieve the desired level of sharpness. Remember to periodically clean the stone surface to prevent debris buildup and ensure consistent sharpening.

Now that your chisel or plane blade is sharp, let’s explore the benefits of using a honing guide.
