I started sharpening my chains with a 12 volt granburg several years ago. Tried to get into hand filing after hearing from many experts on this site. I quickly decided it sucked! The wood I cut is too dirty, I go through a chain every 20-60min without touching the ground. I finally bought a 511ax, and its the best thing I have ever purchased. My first slab cuts with the 660 were as flat as glass, how could I have cut wood for so long without one?
