Seconding what others have said...

I've used straights honed by three of the top honemeisters here, and none of them were as sharp as a commercial razor in my opinion. That being said, we're talking apples and oranges here. The cutting action of both is entirely different.

(I think the straight edge is slightly more rounded, especially after stropping, and it rides along on the skin. This pushes the skin down exposing the whisker a little lower before cutting. By riding on the skin, the blade edge doesn't shave off a layer or two of dead skin cells like Shavettes. That's my theory.)

I prefer a straight shave to a Shavette-like shave. Just feels so much better.
