Just a small point, but many German razors (made according to metric sizing) that are classified here as 6/8s actually measure closer to 13/16s.

If you check out the Dovo razors offered at www.classicshaving.com you'll see that almost all the razors are listed as 5/8s (11/16s). As I recall, it is only their new Bismarck that is 6/8s (13/16s). On the otherhand, their TI offerings have quite a few larger blades listed as 6/8s and 7/8s.

That being said, awhile ago I set up a good friend with some shaving gear and started him out with some good quality 5/8 razors. I recently sent him a larger blade (that I originally got from John Crowley) for him to try. He's only just started shaving with a straight recently and told me, with his large hands, that he found the bigger blade easier to use.
