Sorry to dig up an old thread here but I have the exact same issue sharpening my PM2 and was wondering if:
A. Will the new arm upgrade help this issue? I have one on order. I suspect it won’t but thought I would ask.
B. Other than sanding the plastic on the diamond hones or using the Choseras, are there any other options that would work with the diamond/ceramic stone?
BTW, love my WE and with a little experience and patience I can get edges better than I ever have in years of other methods 🙂
