I used to hand file everything. I'd free hand a chain 'till I got the angles outta whack, then I'd put the manual sharpener on and straighten it up. I'd never take a chain off 'till it was worn out. Since then I bought an Oregon grinder from Northern and use it now. My hands and arms can't take the hand filing anymore. Be careful with the grinder though, you can knock the temper out of the teeth.
