Just adding to the resources:
A fellow Canuck has set up a site worth checking out:
www.Refinedshave.com
He's a DE razor user and material science nerd (who also shaves his head!) who wanted to get some harder numbers on the sharpness and longevity of DE razor edges.
He uses a saddle and jig to get consistent cutting repeatability on weight required to slice a standardized thread media. His website tables are a bit messy, and his review comments aren't really reflected in the summary tables, but if you find interesting data and look up his review it's good stuff. He's testing more blades all the time, if you subscribe he sends emails when he's getting ready to buy new blades or when he publishes new reviews.
So far the data he's compiled makes a lot of sense. The super-sharp Feather, Voskhod and Personna blades are performing as their devotees expect.
The biggest news is not which blades are sharpest, but which are most consistent. (Some blades are a okay on the first shave, super sharp next shave after the PTFE coating is gone, then dull the third shave. This means you have to adjust your expectations/technique.)
I like Feather blades in my old Gillette adjustable, since I can dial in an aggressive/sharp edge where I need it but dial back a mild shave for my tender swirly-grained neck and not lose performance. I'm probably going to try Voskhod when my last Feather goes (bought a pack of 100 about 18 months ago.)
