What I get from the article is the edge is damaged: By corrosion and distortion. The strop cleans the corrosion and realigns the the bent edge. I feel that the razor has let me down if it cannot complete a shave without needing to be stropped.

On the few occasions I have tried mid shave strop. it helped. I assume it is misalignment via first pass. Could be angle, face wire, edge too thin...

Realistically I bet all my shaves would be improved by doing it. I just don't want too, manage without it. It can be nice but not necessary. I also shave directly off the hone and sometimes skip a stropping to get a better feel for whats happening in the invisible world of sharp. But I have never stopped stropping all together to see how long a given razor will go.

if you're thinking you may need to grow a gotee and stropping helps_ god speed
