je pense qu'il faudrait avoir une meule de polissage moins large que la lame pour ne pas atteindre les bord: si la lame fait 4mm il faudrait essayer une meule de polissage de 3mm ou3.5mm ?
I used 3D-printed tool, which is my own design for the polishing. So I didn't use power grinder for polishing. My tool should not touch the edge in the way that it rounds the edge, but still it happens. I do not fully understand why.
Today I tried proposed tape trick. Not with Kapton tape, just with normal office tape. It helped a bit, but did not prevent edge rounding. @@issacasimov

Maybe tape the edge with like Kapton tape
I think tape will not help, but I can try that also@@issacasimov
