Filing rakers

I have always had a problem filing rakers. Hard for me to tell when the flat spot left after jointing "just disappears", then after swaging and filing to the final depth, , did I get rid of that flat spot so the raker tip isn't a "sled runner". Then I remembered my old (had it a looong time) 30x handheld illuminated microscope. What a serendipitous discovery! Now I have a way to be precise when doing those operations. I don't have to be fast but I do like to be precise, which is what we are after in the end.

I think you are correct Bob, if you can not see a tiny spot of light on a raker or cutter or confirm a razor sharp edge on the same you can't do a good job of sharping. I had not seen the pocket microscope before but I use a head mounted magnifier.
Here are some ideas on lighting and viewing a saw when sharping:
