Ranking by blade gap size
The following, based on a measurement of blade gap and razor weight, will hopefully agree with most of the impressions of the shaving community. This list was compiled by multiple people; inaccuracies are bound to result, and therefore multiple listings for the same razor are possible and even desirable. If there is only one measurement of a given razor gap, it assumes very strict manufacturing tolerances and that the razor measured has not ever been dropped, etc. which we know to not be the case.
The easiest way to measure the blade gap is with a feeler gauge. How to do it is described here.
