I first tried it on a chain that was already on my saw that wasn’t really dull but it could used some refreshing up done. The tool seemed to work rather well but like I said it wasn’t really dull to begin with.

Up next came the real test when I took off the freshly sharpened chain and put on another chain that was really dull and I failed to get it sharp with just a file.

It look me a little bit to get it seated on there just right but once it was in place I managed to get the chain sharpened and when I tested it out today it cut like a brand new chain.

Bottom line this chainsaw sharpener really works though it is a bit pricy on the pocketbook to purchase but in the end it’s going to save me a lot of headaches and hassles.
