snooze ,, yes ive read that not oiling them actually ruins the blade itself, but some of the people i talked to said that they take a fair amount of time to sharpen each blade with all the turning an redoing each side several times , tell me please how many times do you actually have to do this for one blade? an they said had to use one set stones then change to the finer one an repeat is this so ? grace co actually said it only sharpens 3 kinds of blades an fiskers an others are to soft for the machine but they dont state this on their pkging.
