Is 600x microscope sufficient?

[SHARPCO]

OK... so, we need to make Grepper's post on 'scopes the beginning of a sticky topic if possible. Please. That's a Fabulous post my friend.

I have had a Veho 400 USB scope for years, but I gotta tell ya, it's seen virtually no use. I can see the LOW plainly and waaay quicker with my 80x toy microscope. If you make a pass and want to see exactly what happened on that pass, how long does it take to absolutely inspect the entire edge with a USB 'scope? What if you're inspecting every pass on a blade... like 10- 20 passes per side?
   
I may not understand, but is there an issue with the LOW? Do we know exactly what we're seeing?

I don't know much about LOW. 

I have a 10X loupe and I believe it couldn't show me LOW and micro burr. 

I'm not having trouble removing the burr, but I want to make sure it is completely removed.
