You need to detach the saw blade from the saw using a wrench. The circular saw blades vary depending on the model. Therefore, there may not be a standard way of removing them. Most importantly, you need to follow the instructions given by the manufacturer on this.

There is no information regarding the tool that you can ever get that is better than what the manufacturers can provide. All in all, remember to follow any safety precautions provided by the manufacturer keeping in mind that you are dealing with a sharp tool. 

Create a Mechanism That Holds the Blade in Place

Create a Mechanism That Holds the Blade in Place

Get a square slab of wood and then attach a cylinder to its center. The cylinder should have a diameter that is equal to that of the hole in the middle of the circular saw blade. After the attachment is done, you secure the slab in place by adding a strip of wood to its bottom.

Complete this step by taking an additional slab of wood then chiseling a strip that goes all the way down of it. Make sure the strip is large enough to hold the strip on the base of the slab with the cylinder.   

When you follow these processes to the latter, you will be able to comfortably sharpen the blades with your Dremel since the slab with the cylinder will have been steadfastly held in place.

Consequently, you can get better results with the sharpening. You can also use a vice fixed to the strip of wood beneath the slab to serve the same purpose as the one described above. 

Make the Blades Accessible

This is the perfect time to slide the blade down the cylinder to make it rest upon the slab. You need to make sure that the tips of the blade hang conveniently over the edges of the slab for better access.

Otherwise, the blades will not be reachable for sharpening. And since without better access you may not be able to sharpen them well, you m need to be keen on how you set it up. 

Prepare the Dremel

Prepare the Dremel

Attach the tiny round cutting head of the Dremel and secure this sharpening device at a ninety-degree angle to your saw blade on its left-hand side. This process will help make the most out of the work that is about to be done here.

Set up the saw blade in such a way that the longer exterior curve of each of its tooth runs against the Dremel. To avoid double sharpening, you have to mark the tooth that is closest to the Dremel.

Begin by activating the Dremel so that it functions while steadfastly secured in place. Afterward, hold the edges of the saw blade and gently brush the outer end of the marked tooth against the functioning Dremel. This may take you about a second or two for each tooth.  

When you are done with one tooth, move the saw blade back and rotate it to bring the next tooth in place for sharpening. Repeat this process until you have gone all the way around the blade and have returned to the marked tooth. This is how you know that every tooth has been sharpened. 

Sharpening the Other Side

When you are done with the left side of the blade, flip the Dremel so that it is on the right-hand side of the blade. Remove the saw blade from the cylinder, flip it around, and sharpen it the same way you sharpened the left-hand side. With that, you should be done.
