With some practice with stropping and a good strop set with a leather and canvas/linen strops a razor can be kept shaving sharp for a very long time. I used only one razor (Dovo Stainless) for about three years with just such a strop. Not even a fancy one - an Illinois 361. With no strop paste added. My report on that experiment years ago is probably still somewhere in the depths of this forum. But practically, I agree with those who say about a year between honings is a good average. And since so little metal is removed with a fine grit hone, honing more often is perfectly fine. (And fun, too.)
