Thanks for your advice. EZE-LAP still hasn't contacted me back. I ordered 3 different types of files from Bob Marriot's....and I will see which I prefer. Then I will put one with my vest, one in my to go fly tying box, and one on my tying desk. Yes, things drop out of your pockets easily, so attaching the file is a very good idea. They make a very small angler's file with a clip attachment, but I will order it later. I did not see one for sale there, but it can wait. With 3 files I will be in business for a while so to speak.
