Determining When it’s Time to Sharpen or Replace a Dull Saw Blade
What can tell you that your saw blade is dull? You might wait for your car to tell you when it’s due for an oil change. Maybe you change the oil every 3,000 or 5,000 miles. But your saw will not send an alert to your cell phone to notify you that the blade is worn out. There aren’t automatic notifications, or a set number of uses to tell you when it’s time to replace your saw blade. You make that determination using your own good judgment.
It doesn’t matter if you use your saw every day, or only a few times a year; eventually the blade wears down to a point where it needs sharpening or replacement.
