Thanks for the link!
I actually benefited from the link, as it gives some nod to the Fingernail Test, which I have used.

She was actually worried when I threw out my disposables and started hunting for blades for my first (Jr. High) DE razor. However, I've pretty much emptied the odd corners holding spares.
Contrary to the Chart, all double edge blades are not the same. Far from it.

I use Feather blades in a Feather Safety Razor. Great balance and stays sharp a while. Interestingly, the same blade in a 1942 Gillette Super Speed does not hold its edge the same way.

For knife blades, I use the fingernail test. I really don't use a test on my edge tools. I have my technique down to where I trust I've done a good enough job to make things sharp.
