You file by hand ?

[KTM rider]

yes filing by hand is the pros way to do it but it takes some basic knowledge of technique and principles or it is a waste of effort.

However if you dont mind buying a lot chains the grinder may be your style, the chain will last 10 times longer by hand sharpening I cut down a lot of trees and brush when wildland firefighting and working for a tree service so I know a little about it
