Update on my experience with the Valet razor and various blades:
Gem Blue Star, slotted and notched to fit: acceptable.
Valet blade, fresh out of the wrapper: bad.
Valet blade stropped 15 times, and then another 25 times, still bad.
Feather blade, fresh out of the wrapper, good.
Valet blade, honed with 3M micro abrasive paper with a home made honing guide, 5 micron and then 1 micron: acceptable.
Valet blade, further honed with 3M 0.3 micron paper, still only acceptable.
Note that my regular razor is a classic Gillette DE razor with any good blade, much less aggressive than the Valet. In that razor, a Feather DE blade is outstanding. By the same standard the Feather SE blade in the Valet razor is only good.
I guess the upshot is that Valet blades are usable only if honed, but not otherwise. I have yet to try stropping the honed Valet blade.
