TIP ON HOW TO GET A RAZORS EDGE WHILE HAND SHARPENING A CHAINSAW 

Great info that most folks don't know about. Thanks for a great video.

Second to your "flush cutting" this video has helped me more than anything. When putting a new chain on I can cut 5 trees in no time. And trying to fire with my old worn out file I wasn't any better off. Threw the old file away and bought several more. Back to cutting good in a few minutes.

Your videos make a lot of sense, thanks. Do you always use full chisel, or are there times that you would use semi chisel?
