I prefer a 6/8" razor over anything smaller, but I agree that there's very little difference between the 5/8" and 6/8" sizes.

Having said this, I find that the larger razor has some advantages, especially when one is first starting out; here are a few:

  • Wider razors are easier to strop. It's easy to lift the spine of a narrow razor off your strop, and you want to avoid doing that at all costs!
  • It's easier to judge blade angle. Blade angle is critical to achieving a close shave, AND to avoiding bloodletting!
  • They generally weigh more. A heavier blade can do more of the work for you, lightening your touch in the process.
  • They hold more lather. Trivial, perhaps. But less rinsing or wiping means more shaving.


YMMV.
