Chain sharpening pro tips.

View attachment 686286 Here is the one that I just grazed with the grinder to get it to 30/50/0. I did this to try and recreate the profile that was working well with the handfiled chain but it was way to grabby on the 461 with 20 inch bar in green silver maple which says a lot. I don’t understand why the hand filed performed different than the ground at what appears to be the same angle

Maybe the angle of your pic but it looks like The leading edge of the cutter has a beak and that will dull quick.
