SAVING A DEAD CHAINSAW CHAIN! | New Oregon Sharpener Test

We put the new Oregon Semi-Pro Bench Chainsaw Chain Sharpener to the ultimate test! I took one of my oldest, most damaged, and completely dull chains and used this machine to bring it back from the dead. We'll do a full step-by-step setup and then take it into the timber yard to see if this refurbished chain can cut through a large Birch tree as well as a brand-new chain straight out of the box. The results are unbelievable!
