FASTEST CHAINSAW CHAIN?! How to square file a chainsaw by hand.

In this video my buddy Inbred Jed sharpens my ms661 with his triangle file in hopes that sharing his knowledge will help you get your saws razor sharp!
I bought this triangle fine on the phone when I called Madsens in Washington State. +1 (360) 736-1336. They also have a website but it’s terrible. I don’t know the brand of the file or where to buy it online so give them a call and order one!
