Regular sharpening is essential to keep your blade in peak operating condition. Sharpening them on a regular basis helps to prolong their life and makes your job easier.

I’ll explain below:

Bow Saw Sharpening: Required Tools

Purchasing the necessary tools for a project is just the first part of the job’s completion. Some basic tools are necessary for sharpening a bow saw blade, and they are listed below.

  1. A vise for sharpening bow saw
  2. Bow saw sharpening files with a triangular bow saw handles
  3. Bow saw sets

Safety Measures

We must wear safety gear, such as lengthy safety gloves and eye goggles since we’re working with sharp items. Secondly, ensure that the saw is properly clamped or otherwise fastened to prevent any movement of the saw while it is being sharpened.

Now that we have what we need, let’s go for the actual method of sharpening your bow saw blade:

1. Set the Saw & Teeth in A Vise

Placing your saw in a bow saw sharpening vise will allow it to be sharpened more effectively. A vise is easily available for purchase at most places. You can also build and modify it in your house to suit your specific requirements. When you’re putting the hand saw in the vice, be sure that the section of the blade that has the teeth is facing up.

To avoid any movement while sharpening the hand saw blade, be certain that just the teeth are visible and the remainder of the blade has been fastened and locked.

2. Clean Up Any Dirt or Rust

To ensure that the teeth are properly sharpened and avoid damaging the file, remove any filth from the blade before using it. Using a liquid blade cleanser, which can be obtained at a hardware shop, may be beneficial. It will also help to remove rust from the blade.

3. Shaping Tooth Tops Smooth and Equal in Height with A File

A diamond file is required to sharpen most current saws. Older blades are composed of weaker metals and may be sharpened using less expensive tools. To avoid damaging your teeth, be careful not to exert too much force on the file.

4. Filing Crosscut Saw Teeth

Choose a file based on the angle and size of the teeth. The file should not cover more than half the teeth when positioned between gullets (teeth gaps). This will prolong the file’s life and prevent premature wear on the inner edge.

To get the greatest results with cross-cut saws, it is recommended to use a three-square file or a cross-cut file for each cross-cut set of teeth.

Your cross-cut hand saw will be a lot sharper when you’ve used the correct file to sharpen it up. When sharpening, you’ll just want a little fleam added to it.

You should double-check your angle gauge to ensure that you have not added too much fleam.

5. Filing Rip Saw Teeth

The rip-cut hand saw is the same. Add a little rake to your filing motion. Use the angle gauge to ensure you’re applying the correct amount of rake. Be sure to look at the teeth for both scenarios.

This movement is employed by various individuals depending on the effects they desire to attain. Do I need to add movements? It all relies on the outcome and the bow saw’s sharpness.

6. Final Sharpening

Start filing after you’ve completed these steps. Aim for 2-3 strokes for each tooth. A cross-cut bow saw requires filing alternate teeth (e.g. 1, 3, etc.). Then switch sides and start filing opposite teeth from the tooth you skipped.

The teeth can be filed and sharpened individually for a rip cut. Remember to switch sides after completing each side. A cross-cut saw requires more than one side change due to teeth’ shape.

7. Go for A Test Cut

After you’ve sharpened your hand saw, the next step is to evaluate its sharpness by making a test cut. If the cut is fast and clean, you’re ready to go; if not, you may want to try honing the set of teeth one more time.


The proper maintenance of a bow saw will ensure that it will serve you for several years.
