I can agree with Glen up to about 87% of the time that it is more the honing than the shave as the determiner of a good shave. Before I started my feeble attempts at honing I was shaving with razors honed by five different people. In thinking back about specific razors honed by one of the five I'd have to say that there might be credence to what kind of stone to use for which brand of razor.

And, to not being accused of being facetious, add the ephemeral qualities of time of day, mental attitude, caffeine level, concentration level and energy level.
