► Only sharpen the cutting edge – do not file
blunt projecting parts of the cutting blade or
the cutting blade guard (see "Main Parts and
Controls")
► Always file towards the cutting edge.
► The file only sharpens on the forward stroke –
lift it off the blade on the backstroke.
► Use a whetstone to remove burr from cutting
edge.
► Remove as little material as possible.
