Step 1: Remove your blade from the saw

Before you start the sharpening process, you first need to remove the blade from your circular saw. Now, you can do this by using the blade release switch if your model offers that option or you can use a wrench to loosen the bolts that keep the blade in its place. If you have the blade release switch then use it because this would make your job infinitely easier.

Step 2: Now hold your blade tightly

Once you have removed your blade from the circular saw, you need to hold it securely in your hands in the upwards direction so that blade teeth are facing towards you.

Make sure that you don’t hold the blade a little too tightly else you could end up warping the blade metal with all that pressure.

Step 3: Make your marks on the blade

Now make sure that you mark the starting point of your blade where you will sharpen it so that you don’t sharpen the same point again.

Also, see that every two blade points have a bevel on their side and then take your file and using the bevel position, keep your blade at a 20-degree angle and stroke your bevel 4 times up and down.

You will be able to notice a considerable difference and if there is no noticeable change, then add a few more strokes to it.

Step 4: Don’t forget the bevel

It is important that you keep a check on the bevel edges and once you’ve done that only then stroke the blades alternatively. Make sure you apply the same number of strokes to all the blade tips.

Step 5: Repeat the process on the other side

Once you have made the round, you need to turn your blade over and then again start with the whole process. Make sure that you mark the starting point again to avoid sharpening your blade tips twice.

You also need to file the tip of all the blades so run your file back and forth once on the front edge of your blade point and avoid multiple strokes as this could wear your blade out. Make sure you file the tips for all the blade tips on your saw blade.

Step 7: Install the blade back into the saw

Once your blade is sharpened properly, you need to loosen your vice grip on it and then install it back into your saw.

These steps are a great way to save some money while giving your saw a renewed life.
