These can do in one hour what my other local files can do in a couple of days. And here you can see the edge has been broken.
Next I sand the filed edge down with wet & dry papers, 3M micro finishing films and lapping films. These are stuck on a brass strip or a toothpick with double sided tape. This helps to get into difficult corners.
.....very time consuming business but worth it. And below, you can see the fruits of my labours.....
Hope you enjoyed this. Aditya
