Looks like you're getting the saw filing basics accomplished. Next step is to tune your blade for better performance. When you point up your cutters, how much of a "dot" (unfiled flat spot which reflects light) do you leave? If you file completely past the dot, you have just shortened that cutter below the jointed height, which will encourage whiskers. When I file my cutters, I first back home them to guarantee clean flat steel. Then I profile them to the near final shape, leaving a dot a little bigger than the period on the end of a sentence. Then, I make one more pass with the hone to remove any filing burr. I then set the tooth, and if over by one or two thousandths, I'll back hone to the exact setting. This still leaves me with a small flat dot which supports my raker gauge for final cutting of the raker height. That done, I final file my points taking care not to file past the dot. For an absolute needle point, I'll glue a strip of 400g sandpaper to a wooden paint stirrer and carefully take the small dot down to near disappearance. This will also polish the face of your cutter. This might sound like a lot of extra stuff, but these final procedures go really fast and don't add much to the filing time.
