So now that it's been a few months which one kept it's mirror finish the longest? I personally love the Infini but the glass falls so fast and stops cutting good after 1 kit th gun primer lasts me 3. The only one I have that's kept it's finish and still cuts the same is a cheep chineese one from DMODE it's just really fine and takes a while to file down nubs.
If it’s not cutting like it did it probably just needs to be cleaned. Dust can get clogged up in it. Try soaking it in acetone or thinner then use a toothbrush to help unclog it.
