I just got my first package and have been working on them too. I use a 14' file flat on the table with med pressure till i get all the sharpie marks gone. Then I do another 10 light strokes per side withe the 14' file. Then I put on an arrow and work lightly(only the weight of the file) with an 8' file and can get them to shave. When I try to finish on a fine waterstone I seem to go backwards and it gets duller?? Maybe I'm not working enough on the stone to get the burr all the way off??
