Additionally, sharp blades make clean cuts that reduce the strain on your saw and result in smoother operation.

3. To Extend the Life of Your Chainsaw

Finally, sharpening a chainsaw with a grinder regularly can help extend the life of your chainsaw. Sharper blades require less energy to cut, so they don’t put as much strain on the motor and other components of the saw.
