Coping saws are C-shaped handsaws that are used for delicate woodworking tasks such as creating cutout shapes in wood and making coped joints in moldings. The blade is a thin piece of metal that extends across the open end of the C. Once the blade becomes dull, it is no longer useful for accurate and easy cutting, and it is also more dangerous since more force is required to get it to cut. This increased force means a greater chance of slipping and cutting oneself.

You may think of sharpening a dull coping saw blade like you would with some of your other saws, but it is usually not worth the effort. Blades with steel teeth can be sharpened on your own, but those with carbide-tipped teeth must be sharpened by a professional. A professional will usually inform you when your blade is not of high enough quality to warrant sharpening. Since a multi-pack of new coping saw blades costs only a few dollars, it is probably not worth the effort to repair an old blade. However, you can keep used, dull blades for when you are working on a demolition project and do not want to ruin your good saws.

To prolong the life of your coping saw blade, it is advisable to wrap it up when not in use. An easy way to protect your blade is to cut open a section of hose or tube and insert the blade into the slit. Before starting your coping saw project, make sure to check that the material you are cutting is free of nails that might damage the blade. Ensure that it is clean so that no abrasive substances wear away and dull your coping saw blade.


1. Can you sharpen coping saw blades?

Yes, coping saw blades can be sharpened. However, it is important to note that not all blades are the same and some may not be worth sharpening due to their quality. Additionally, sharpening coping saw blades requires some skill and the use of specialized tools such as a triangular file.

2. How do you know when a coping saw blade needs sharpening?

You can tell that a coping saw blade needs sharpening when it starts to cut less efficiently or leaves a rougher cut than usual.

It is better to sharpen the blade before it becomes completely dull to ensure that it lasts longer.

3. What are the benefits of sharpening coping saw blades?

Sharpening coping saw blades can extend their lifespan and improve their performance. A sharp blade will cut more efficiently and leave a smoother cut, which is important for precision work. Additionally, sharpening the blade can save you money in the long run since you won’t have to replace it as frequently.

4. Can you sharpen a coping saw blade without a triangular file?

While a triangular file is the most effective tool for sharpening a coping saw blade, it is possible to use other tools such as a round file or a honing stone. However, these tools may not be as effective and could potentially damage the blade if not used correctly. It is recommended to use a triangular file for the best results.

5. How often should you sharpen coping saw blades?

The frequency at which you should sharpen coping saw blades depends on how often you use them and the quality of the blade. If you use the saw frequently or for heavy-duty work, you may need to sharpen it more often. As a general rule, it is recommended to sharpen the blade every 10-15 hours of use or when it starts to show signs of dullness or damage.

6. Can you sharpen coping saw blades yourself or do you need a professional?

Sharpening coping saw blades can be done by yourself, but it requires some skill and the use of specialized tools. If you are not confident in your ability to sharpen the blade, it may be best to take it to a professional.
