I have to disagree fundamentally with the comment about a double bevel not being as long lasting as a single, the raw physics at work dictate that a steeper bevel produces a more resilient edge.

It's like the difference between a Sushi chef's ultra fine Sashimi knife that would probably shave your face as well as any brand new TI, and his Cleaver, which, while intentionally not sharpened to the same degree, has a much more robust grind to withstand the force of chopping through hundreds of pounds of tuna spine without incurring any damage.

Granted this is a dramatization, but there is no way a steeper bevel should deteriorate faster than it's more acute counterpart, if indeed the steels are of identical quality, and the same abuse imparted to them.

There may be an issue with stropping the micro bevel to the same degree as a traditional edge, and thus leaving the edge in worse condition after each shave, but it shouldn't be an issue of the actual process being inferior.
