Between number 3 and number 7, it was instantly to me which had more accutance and sharpness. Number 7 of course, which happens to be the P45 file. I don't know about the rest because my eyes are very tired. It is 2:27 am in Tulum.
Thanks for the effort. I wish I could not see the difference, but this time it is obvious. P45 wins hands down.
Have a nice weekend.
