Thank you very much for your help M1rrorEdge!
I think I will follow your advice, and go for the films.
Only question is, how long do they last?
I mean, should I get one of each, or am I going to be left with nothing but glass in less than 5 sharpening and then have to place another order?
The diamond pastes (especially the really thin ones) are pretty expensive, and I don’t think I will try to mess with convex grinds in the near future.
I could invest on them if I find it necessary in the long run.
So, the cube is a good idea, and so is the low angle adapter. Happy to hear that.
Concerning the microscope…
I do not know if the rules of the forum allow it, but can I post a link from the shop I plan to purchase the WE and help me check if they offer such a microscope?
