Sounds like a good topic for another thread... :)

I've used microscopes up to 1000x; For me, the stereo microscope is more useful - even with the lower magnification.

I've had a few PMs asking about my microscope setup.

What I'm using is overkill for just taking pictures of blades.
I have this stereo microscope: Sharp Stereo Microscope 20X-40X-80X and I have a...

Stepped up a grit, and the edge is really chippy:

I cropped this one a little tighter - it's about 80x.

Noteworthy: The edge at this point will cut arm hair effortlessly.


I think...

I think I'm going to do more threads like this - I like the way it's evolved.

Here's what it looks like after 30 laps on a Chosera 600:

I stropped it and took this picture.

The magnification on this one is about 180x:

The red lines indicate the microbevel. Everything above that in the image is part of the bevel.

Yes it is. :)

I suspect that there is enough of a microbevel there to allow it to shave, but that the metal is very thin and fragile enough to fold from just cutting beard hair.

Another piece of the puzzle, and things are starting to make a little more sense:

I was curious about the small burr at the edge; I wanted to see if I could get a better idea about what's going on...

Ok, I got a little sidetracked today... Pics and results to come later tonight or tomorrow morning.

What's interesting about this particular blade is that it is capable of cutting hair and giving...

Awhile ago, a member posted about a problem razor that wasn't giving satisfactory shaves, despite multiple honing efforts and passing all tests preliminary to the shave test. The particular brand,...
