How to Sharpen a Blade
- 1). Remove your saw blade from the saw (generally, it's a matter of using a wrench to loosen a bolt at the center). Put the blade in your vise, gripping it just below the center hole.
- 2). Make a pencil mark on one of the teeth so you'll know when you've gone all the way around the blade.
- 3). Position the tip of your file in the well of the first beveled tooth edge that's facing you. (The directions of the bevels will alternate.) Run the file forward in a gentle but firm stroke, in the same direction as the bevel, for the full length of the file, moving upward along the tooth and off the point. Lift the file, return the tip to its original position, and repeat two more times, filing in the same direction each time.
- 4). Repeat the process on each of the bevels facing you, skipping each of the ones in between that are facing the other side. Continue until you get to the vise, then loosen the vise and rotate the blade so you can get at the rest of the teeth. Continue sharpening every other tooth until you get back to your pencil mark.
- 5). Loosen the vise, flip the blade so the other side is facing you, and repeat the whole process on the bevels from the other side.
