not all of the individuals that are not in agreement are moderators. I happen to agree with Austin. Why would you want to dull a razor blade?? Would you want to do that with a straight razor? Of course not!!! so why do it with a DE blade? If a blade is too sharp then try another that is not as sharp and fits you better... you do have that option. Rather simple really...
If it works for those who have tried it then more power to you all. As for me I will keep on shaving with the sharpest straight I own as this is what works best for me.

The Feather AC blade is where the corking method was first thought to originate before it spilled over to DE blades. Having read the threads from Joe Lerch and Dr. Chris Moss over at SMF and others at SRP, I doubt that there is a traditional straight blade as sharp as a laser cut Feather AC blade. Joe says that he has had straights honed by the best honemeisters and none were as sharp as an AC. Dr. Moss says that he discards his Feather AC blade when it's sharpness diminishes to that of a traditional straight. So if "sharpness" was the only factor for a great shave, everyone would be using a Feather AC or Feather DE blade. But everyone does not use these blades, so there must be other factors that contribute to getting a great shave besides sharpness.
Words like "harsh" and "unforgiving" are used by critics of the Feather AC blade, but in my experience corking can tame the blade. Traditional straight shavers have the advantage of being able to custom hone and strop their blade to a sharpness and smoothness appropriate for their face. Newbie straight users are always admonished not to accept a vendor's claim that their newly purchased traditional straight blade is "shave ready". They are always told to send it to a hone meister. Until corking, DE shavers were not afforded the same customization option for the supposed "shave ready" DE blades.
mparker also posted that Schick strops their DE blades. I don't believe that any manufacturer would go through the extra time and expense of a "finishing step" for their blade if there was no value in doing so.
Like some DE shavers, I also don't believe my AC blade is being dulled by corking. If it is dulled by corking, it is only marginally so and still very sharp. Probably still sharper than a freshly honed and stropped traditional straight. Unlike the DE world, I cannot change to a competitor's blade since I only have one choice of manufacturer (barring the Schick injector blades), so corking is the obvious solution.
